Apple iPhone 5 review

David Pogue, The New York TimesSeptember 19, 2012


















If you were taking a college course called iPhone 101, your professor might identify three factors that have made Apple's smartphone a mega-success.

First, design. A single company, known for its obsession over details, produces both the hardware and the software. The result is a single, coherently designed whole.


Second, superior components. As the world's largest tech company, Apple can call the shots with its part suppliers. It can often incorporate new technologies - scratch-resistant Gorilla glass, say, or the supersharp Retina screen - before its rivals can.

Third, compatibility. The iPhone's ubiquity has led to a universe of accessories that fit it. Walk into a hotel room, and there's probably an iPhone connector built into the alarm clock.
If you had to write a term paper for this course, you might open with this argument: that in creating the new iPhone 5 ($200 with contract), Apple strengthened its first two advantages - but handed its rivals the third one on a silver platter.

Let's start with design. The new phone, in all black or white, is beautiful. Especially the black one, whose gleaming, black-on-black, glass-and-aluminum body carries the design cues of a Stealth bomber. The rumors ran rampant that the iPhone 5 would have a larger screen. Would it be huge, like many Android phones? Those giant screens are thudding slabs in your pocket, but they're fantastic for maps, books, Web sites, photos and movies.

As it turns out, the new iPhone's updated footprint (handprint?) is nothing like the Imax size of its rivals. It's the same 2.3 inches wide, but its screen has grown taller by half an inch - 176 very tiny pixels.
It's a nice but not life-changing change. You gain an extra row of icons on the Home screen, more messages in e-mail lists, wider keyboard keys in landscape mode and a more expansive view of all the other built-in apps. (Non-Apple apps can be written to exploit the bigger screen. Until then, they sit in the center of the larger screen, flanked by unnoticeable slim black bars.)

At 0.3 inch, the phone is thinner than before, startlingly so - the thinnest in the world, Apple says. It's also lighter, just under four ounces; it disappears completely in your pocket. This iPhone is so light, tall and flat, it's well on its way to becoming a bookmark.

Second advantage: components. There's no breakthrough feature this time, no Retina screen or Siri. (Thought recognition will have to wait for the iPhone 13.)
Even so, nearly every feature has been upgraded, with a focus on what counts: screen, sound, camera, speed.
The iPhone 5 is now a 4G LTE phone, meaning that in certain lucky cities, you get wicked-fast Internet connections. (Verizon has by far the most LTE cities, with AT&T a distant second and Sprint at the rear.)

The phone itself runs faster, too. Its new processor runs twice as fast, says Apple. Few people complained about the old phone's speed, but this one certainly zips.
The screen now has better color reproduction. The front-facing camera captures high-definition video now (720p). The battery offers the same talk time as before (eight hours), but adds two more hours of Web browsing (eight hours), even on LTE networks. In practical terms, you encounter fewer days when the battery dies by dinnertime - a frequent occurrence with 4G phones.

The camera is among the best ever put into a phone. Its lowlight shots blow away the same efforts from an iPhone 4S. Its shot-to-shot times have been improved by 40 percent. And you can take stills even while recording video (1080p hi-def, of course).
So far, so good. But now, the third point, about universal compatibility.
These days, that decade-old iPhone/iPad/iPod charging connector is everywhere: cars, clocks, speakers, docks, even medical devices. But the new iPhone won't fit any of them.

Apple calls its replacement the Lightning connector. It's much sturdier than the old jack, and much smaller - 0.31 inch wide instead of 0.83. And there's no right side up - you can insert it either way. It clicks satisfyingly into place, yet you can remove it easily. It's the very model of a modern major connector.
Well, great. But it doesn't fit any existing accessories, docks or chargers. Apple sells an adapter plug for $30 (or $40 with an eight-inch cable "tail"). If you have a few accessories, you could easily pay $150 in adapters for a $200 phone. That's not just a slap in the face to loyal customers - it's a jab in the eye.

Even with the adapter, not all accessories work with the Lightning, and not all the features of the old connector are available; for example, you can't send the iPhone's video out to a TV cable.
Apple says that a change was inevitable - that old connector, after 10 years, desperately needed an update. Still, Apple has just given away one of its greatest competitive advantages.

The phone comes with new software, iOS 6, bristling with large and small improvements - and it's a free download that also runs on the iPhone 3GS, iPhone 4 or iPhone 4S.
The chief attractions of iOS 6 are a completely new GPS/maps app (Apple ditched Google Maps and wrote its own app); new talents for Siri, the voice-activated assistant (she now answers questions about current movies, sports and restaurants); and one-tap canned responses to incoming calls (like "I'm driving - call you later").
There's a new panorama mode for the camera, too, that comes in handy more often than you might expect. As you swing the phone around you, it stitches many shots together into a seamless, ultra-wide-angle, 28-megapixel photo. Unlike other apps and phones with panorama modes, this one is fully automated and offers a preview of the panorama that materializes as you're taking it.

Should you get the new iPhone, when the best Windows Phone and Android phones offer similarly impressive speed, beauty and features?
The iPhone 5 does nothing to change the pros and cons in that discussion. Windows Phones offer brilliant design, but lag badly in apps and accessories.
Android phones shine in choice: you can get a huge screen, for example, a memory-card slot or N.F.C. chips (near-field communication - you can exchange files with other N.F.C. phones, or buy things in certain stores, with a tap). But Android is, on the whole, buggier, more chaotic and more fragmented - you can't always upgrade your phone's software when there's a new version.

IPhones don't offer as much choice or customization. But they're more polished and consistently designed, with a heavily regulated but better stocked app catalog. They offer Siri voice control and the best music/movie/TV store, and the phone's size and weight have boiled away to almost nothing.
If you have an iPhone 4S, getting an iPhone 5 would mean breaking your two-year carrier contract and paying a painful penalty; maybe not worth it for the 5's collection of nips and tucks. But if you've had the discipline to sit out a couple of iPhone generations - wow, are you in for a treat.
It's just too bad about that connector change. Doesn't Apple worry about losing customer loyalty and sales?
Actually, Apple has a long history of killing off technologies, inconveniently and expensively, that the public had come to love - even those that Apple had originally developed and promoted. Somehow, life goes on, and Apple gets even bigger.

So if you wanted to conclude your term paper by projecting the new connector's impact on the iPhone's popularity, you'd be smart to write, "very little (sigh)." When you really think about it, we've all taken this class before.

Terahertz bandwidth could make cellphones 1,000 times faster



Forget 3G and 4G. In fact, forget about the gigahertz frequency altogether—a team of researchers at the University of Pittsburgh say they've managed to devise a means of transmitting data thousands of times faster.

The team led by Hrvoje Petek, a physics and chemistry professor in Pitt's Kenneth P. Dietrich School of Arts and Sciences, successfully created what they call a "frequency comb" that "spans more than 100 terahertz (THz) of bandwidth by exciting a coherent collective of atomic motions in a semiconductor silicon crystal."

The frequency comb is created by the division of "a single color of light into a series of evenly spaced spectral lines for a variety of uses."

What that means is that Petek and his colleagues have devised a structure that could theoretically transmit data to devices like cellphones and computers in the terahertz frequency region—and in fact observed reflected light oscillating at 15.6 THz during their experiments.

The research was published in the March 4 issue of Nature Photonics and summarized on the University of Pittsburgh website.

Petek said the team has discovered "a physical basis for terahertz bandwidth," which could potentially be used to leverage the "portion of the electromagnetic spectrum between infrared and microwave light" to transmit at rates several orders of magnitude faster than today's conventional wireless electronics with bandwidth limited to the gigahertz frequency.

"The ability to modulate light with such a bandwidth could increase the amount of information carried by more than 1,000 times when compared to the volume carried with today's technologies," Petek said.

"Needless to say, this has been a long-awaited discovery in the field."

The scientists worked with silicon, the material used to fabricate the semiconductors at the heart of computing's process technology. Petek said his team expected to hit 15.6 THz in its experiments, the "highest mechanical frequency of atoms within a silicon lattice."

The University of Pittsburgh researchers are actually aiming even higher, or rather faster. By studying the coherent oscillation of electrons, Petek and his colleagues believe they can harness "light-matter interactions" in the petahertz-frequency range, or 1,000 times faster again than the terahertz oscillations they've already achieved.

Facebook launches Interest List, allows users to create personalised newspaper

Facebook has announced a new feature called the Interest List that allows users to compile “interest lists” around topics, wherein the top stories from each interest will appear on newsfeed. The new feature will be rolled out in the coming weeks, and will allow users to create a list in which they can subscribe to their friends, brands, celebrities and others present on the social network. The new Interest List feature on Facebook is similar to Twitter's list feature or Google's Reader, which allows users to create a small list of subscribed social news. However, Facebook's Interest List is much easier to curate and customise news feeds. The social networking giant says its new feature turns the service into a personalised newspaper. Facebook users can create their own lists and share them, or can keep them private. Users can also subscribe to lists shared by others. "Interest lists can help you turn Facebook into your own personalised newspaper, with special sections—or feeds—for topics that matter to you. You can find traditional news sections like Business, Sports and Style or get much more personalized—like Tech News, NBA Players, and Art Critics," Eric Faller, a Facebook software engineer, wrote in a blog post. With the new Interest List, Facebook is now trying to fill up the gaps which it had left. The social networking giant recently updated its photo viewer. The new Interest List will definitely allow Facebook to grab attention of those who have been using other social networks such as Twitter and Google+ to create a personalised information.

Gaming News

The Two most awaited Games coming by the end of this October.

Ubisoft To Release Assassin’s Creed III On October 30

Ubisoft will release Assassin’s Creed III on October 30, it said during a call with investors on Wednesday.

Arriving less than one year after the release of Assassin’s Creed: Revelations, Assassin’s Creed III is expected to star an all-new protagonist in an experience Ubisoft CEO Yves Guillemot said will be “the biggest launch in Ubisoft history.”

Guillemot explained that the developer has been working diligently on the new game for three years, describing what the team has achieved in that time as “fabulous.”

While Ubisoft has yet to reveal where exactly Assassin’s Creed III will take place, the game’s setting has been speculated to be anywhere from Ancient Egypt to the American Revolution. Imagine performing Assassin’s Creed‘s trademark Leap of Faith off the Great Pyramid of Giza. Of course, Assassin’s Creed III‘s storyline will also finally be bringing the story arc of the main Assassin’s Creed trilogy to its long-awaited conclusion.

Ubisoft has not said what platforms for which it will release Assassin’s Creed III, but it will most likely be coming to Xbox 360, PlayStation 3 and PC (and maybe Wii U).

EA to Release Medal of Honor Warfighter in October

Electronic Arts studio Danger Close is currently developing Medal of Honor Warfighter, the sequel to 2010′s military-themed first-person shooter, the company said on Thursday.

Along with the announcement, EA shared an image from the game of a rather angry-looking soldier gripping a rifle, which the company describes as “a visual inspiration and representation of this title.”

EA says it will release Warfighter this October. It is using the Frostbite 2.0 graphics engine to power its visuals, which was also used in Battlefield 3.

Aside from confirming the existence of Warfighter, EA promises to reveal more concrete details about the new game in “the next few weeks.” But if you can’t wait until then, the game is also featured on the front cover of the April 2012 issue of Official Xbox Magazine US, which hits newsstands on March 6.

2010′s Medal of Honor received mixed reviews. Let’s hope that EA addresses some of the previous game’s more glaring issues when it releases Warfighter later this year.

Android is coming to everything ... everywhere


We spend a lot of time talking about operating system market share and usage share, but could Android explode to the point where it make such data irrelevant?

When we talk about Android market/usage share, we’re usually thinking about devices like smartphones and tablets. It seems that knowing how many people use a particular thing is important to some people (I’m not sure why, maybe it helps people think they’ve made the right choice or something). But Android isn’t confined to just smartphones and tablets. Chances are that if you have a gadget like a personal media player or an ebook reader or an in-car GPS receiver, it’s powered by Android. It might not say Android anywhere, and people might not know that it’s Android, but it’s there nontheless.

Android is already all around us, and pretty soon the OS is going to be in a whole lot more places. The next device that Android is set to invade is the TV set. Given the operating system’s heritage in media it seems like a good fit. It’s going to take a long time for people to replace their dumb TVs with Android-powered ‘Smart TV’ sets, but it will happen (people on the whole seem to keep their TV sets for a lot longer than they do cellphones, tablets and PCs).

The TV is just the start of things in my opinion, and it’s the beginning of an in-home Android revolution. As the price falls on low-power computers it becomes feasible to fit make things ’smart’ … smart oven, smart microwave, smart refrigerator, smart washing machine. smart thermostat. Heck, why not go the whole hog and have smart lights and smart doors too?

Smart devices are the next step in evolution for devices that have traditionally been dumb devices. And one of the keys to making dumb devices smart is the a flexible operating system.

Android offers just that.

Note: One company is going to absolutely love it if Android is everywhere … Microsoft. The Redmond giant already pulling in millions every year from patent deals struck with smartphones and tablets makers.

I can see Android in other places too … watches (now there’s something that needs revolutionizing), cars, binoculars, telescopes, home automation devices, remote controls and much more. Android’s power is its versatility, and it is that versatility that allows the platform to be customized and tweaked for a whole variety of applications. It’s because of this that I see an explosion in Android usage over the next few years.

Do you see a day when Android is everywhere, or do you think that the whole ’smart’ revolution is wishful thinking by electronics manufacturers?
