The Apple iPad 2 Review
by Brian Klug, Anand Lal Shimpi & Vivek Gowri on March 19, 2011 8:01 PM ESTVideo Quality
The rear facing camera is native 1280x720 and unsurprisngly captures 720P video. It's essentially the same quality as the iPod Touch, which doesn't come as a surprise at all. There's been considerable discussion about whether this back sensor is optimized (or intended) for video. Given that 1280x720 size, it seems obvious this is likely the case. As we'll show, video on the iPad 2 is actually very good, it's still capture that suffers.
In all honesty, 720P video capture on the iPad 2 is almost as good as the iPhone 4. In addition, there's no apparent change in magnification when switching into video mode on the iPad 2 like there is on the iPhone 4. This is again because 160 pixels are tossed away on the left and right sides in still mode. Unfortunately there's no way to capture a 1280x720 still from the iPad 2 unless you shoot video and manually grab frames. Video on the rear facing camera is captured at 1280x720 at 29.970 fps H.264 Baseline (1 reference frame) at 10.6 Mbps. Audio is 1 channel AAC at 64 Kbps.
Like other iDevices, you can view the actual aspect correct capture frame by double tapping on the preview.
I took two video samples with the iPad 2, one at our usual bench location in afternoon lighting, another outside the local cafe at night to show low light performance. As usual we've uploaded both to YouTube as well as hosted originals in a big 7-zip (186 MB).
The iPad 2's 720P rear facing video capture sample in daylight is actually pretty impressive and on par with all the other iDevices. Apple still has class leading quality at 720P even when competitors are doing encodes at 1080P, and at this point it looks like their ISP and encoder is roughly the same as the A4's.
I also took one more video at another location at night. I start outdoors and then go indoors into a cafe to give a feel for low-light performance.
Front facing video isn't super impressive on its own, but again on par with other iDevices. It's 640x480 (VGA) at 29.970 fps H.264 Baseline (1 reference frame) at 3.5 Mbps. Audio is 1 channel AAC at 64 Kbps.
In spite of being just VGA the front facing video quality is quite decent. No doubt Apple is making a concious effort to go with lower resolution sensors (but with bigger pixels) instead of pushing for more megapixels on the front camera. It's a tradeoff that makes the front facing cameras on iDevices better in low light. Until FaceTime gets HD on mobile devices (and we get more mobile upstream bandwidth), VGA seems good enough.
Still Quality
It's still quality on the rear facing camera that's really disappointing. Still images are again cropped to 960x720 (4:3). The images are simply noisy and underwhelming all around. The competition is shipping higher resolution front facing cameras than what's in the iPad 2's rear facing camera, and the result is that the thing feels like it's saddled with two sub-par cameras.
We've done the usual thing and taken photos with the front and rear facing cameras in our smartphone lightbox and at the bench locations. In addition I shot photos with the iPad around town and everywhere I carried it with me.
The front facing camera seems to have some odd white balance issues, as it shows a reddish cast in our lightbox. Out in the wild, I never ran into any serious performance issues with the front facing camera, and honestly VGA seems fine for the time being until mobile devices get the bandwidth to juggle 720P videoconferencing.
I guess the issue I have with the iPad 2's cameras is that the back one already seems woefully insufficient. Apple has already demonstrated that it's possible to both have a thin device and awesome cameras with the iPhone 4. Coupled with onboard HDR, the iPhone 4 still delivers images that rival all but Nokia's best. It's just puzzling why a device that costs substantially more out the door than the iPhone 4 delivers such subpar still capture quality. In reality, thickness is probably the most important constraint here, as the iPhone 4 is thicker than the iPad 2 and thus Apple couldn't simply toss the iPhone 4 cameras inside the iPad 2. I won't speculate about Apple's motivations for going with these cameras, but the end result is a rear camera that honestly doesn't impress.
Compared to the Xoom
The Motorola Xoom's 5MP Rear Facing Camera
The Motorola Xoom's rear camera captures at 2592 x 1944 (5MP) and is assisted by an LED flash. This gives the Xoom's rear camera a 7.29x higher pixel count than what Apple offers with the iPad 2. But do more pixels mean a better looking picture? Well in this case, yes.

The iPad 2's rear camera predictably produces very saturated colors like the iPhone 4. The rear sensor is very noisy in low light situations and it's not very sharp on top of that. You'll also notice that Apple's funny white balance algorithm acts up in the shot with two external lights vs. one external light.
The Xoom by comparison is pretty consistent in terms of white balance. Motorola also produces a sharper image, although the colors are far too hazy. If Apple over compensates for color saturation, Motorola tones it down a little too much. The LED flash keeps the shot with no external lights from becoming too noisy but it also royally screws up the white balance, making the image a bit too green.
As we mentioned in our review, the Xoom is surprisingly potent when it comes to taking pictures. It's by no means great, but it's way better than the iPad 2.

"you cant be a very tech inclined person if if you think you are, if you dont know that 1.2 GHz quad core arm cortex is coming later this year and so most tech people are waiting on that to happen"Really? You're going to buy that crappy 1.2GHz quad core A9? You're not going to wait the even better 1.8GHz quad core A15 that will be available in late 2012? Sucker!
Personally I think that if you buy now, before the 802.11s wireless spec is standardized, and before the chipsets support OpenGL 6, you're just throwing your money away. But I tell you, come 2020, that's going to be one SWEET rig that I finally get round to buying.

"Just to test it out, I shot a series of videos of my car and stitched them together using iMovie, then added some titles and a soundtrack."I found iMovie completely useless on my iPhone 4 and iPhone 3GS because I could not combine two clips/videos nor could I make a runing commentary with titles.
Are you sure that the iPad 2 version can do this or were all the "videos" in the "series" made from the same longer video?

"Lately Apple has been trying its hand at first party case solutions. It stated with the bumper on the iPhone 4, carried over to the original iPad, and continues now with the iPad 2."When you fix that typo ("stated" instead of "started"), you may also want to correct that fact about what came first.
The iPad launched before the iPhone 4 so the official iPad case launched before the iPhone 4 bumper case, unless I somehow missed it and the official iPad case came out mid-life for the iPad.

pja: The 64gb 3G version was at most $1049 AUD rrp, before the price drop, the 64gb WiFi one was $899 AUD rrp. The 64gb WiFi was never $1100 AUD unless you were looking at eBay pricing while stock was scarce. Anyway as this article states, the iPad, provided it does what you require, is a great combination of battery life, weight and size. Tablets certainly aren't for everyone though.Deepcover96: Agreed. Hopefully this changes later and I'm sure it will, but for the moment Android has a poor selection of AAA titles. Nothing like Garageband or iMovie, but certainly nothing like Infinity Blade, Nanostudio, Beatmaker 2, World of Goo etc. I'm sure Gameloft and EA will eventually do more, provided they can monitize ok on Android. And for the limitations of iOS apps, I wouldn't be able to have an iPad as my only portable device if it were not for Pages/Keynote/Numbers/TouchDraw/Photogene and so on.
CZroe: iMovie for iPhone (last year even) could do what you ask after the first update. This year it's greatly improved. A downside to this app and other Apple apps can be a lack of well known gestures. People don't know in Pages that if you hold your finger on an object, swiping with another finger moves it by one pixel, swipe with two moves it by 5 pixels, and so on. Likewise in iMovie, you swipe down through footage like you were cutting it at the playhead to make a cut. Each cut is a faultless transition, but then you can title each cut area separately. So you cut where you want the text to change, and label accordingly. In the new iMovie (only used on iPhone 4 as I sold 1st gen iPad whilst waiting for iPad2) when you import video there are standard iOS movie trim handles over the clip, you only need import the bits you want from each clip. But you could definitely always import more videos into one project in the last version. I think Apple need a modal help "Would you like to watch a short video about iMovie?" dialog or something on the first few launches with a website link, all these apps have their features tucked away so people often think they're less powerful than they are. I'm not sure Apple is choosing the best ratio of controls to expose to the user here. And yes, iPad case came out before iPhone 4, definitely.

An awesome free web browser for the iPad is Terra, it gives you tabs, has an incognito mode. etc I would definitely check it out.darwiniandude - Monday, March 21, 2011 - link
Thanks, I'll check it out. I only use iCab as I bought it for iPhone, it got a universal update and I've been happy enough not to bother looking elsewhere. (it does have a 'privacy' mode) also caching of pages for when you're offline. Anyway, I've downloaded Terra and will play with it on the new iPad. It looks nice.Ha, there's a Terra Incognito HD game, lol

Looking at the rounded back of ipads, ipad2 in particular, it's hard to understand, why the newer version is easier to hold.With rounded surface, they both should be harder to hold, and ip2 in particular.
darwiniandude - Monday, March 21, 2011 - link
The original had flat sides, probably about 4 or 5mm, and a giant convex back, domed in the centre. The new one is thinner, has no flat sides (the curve just falls away from the front) but it's more of a bevelled edge, and once you're about 1cm in from the edges the back is perfectly flat.Is it easier to hold? Dunno, haven't got mine yet :) But that's what people are saying.

Everyday I use my Ipad even when I don't think about it.I use it as my wake up Radio clock via TuneIn Radio app. This app is great as I can go to sleep with the timer and then wake up to Internet radio which beats the hell out of analog radio. I been looking at a digital radio for a while but there is no reason now for me in the world to do that, and digital radios aren't cheap, it is just another device the Ipad as replaced perfectly with much better screen interface, and life time of free updates as app software evolves.
I think the Anandtech authors here saying that they found them selfs not using their original Ipad1 after a while didn't adapt their imaginations enough of where it can be used, maybe it is something to do with age and being hardwired into their life styles, dare I say it but becoming 'old school'.
I am wondering how they wake up in the morning, I find it hard to believe there is a better way to wake up in the morning then from an Ipad radio app, if it is about sound quality there are plenty of speaker options.
For people who don't get it then I say you just don't see things the same way, I would rather shove a pine cone up my backside then wait more then 2 seconds to be able to look at my email. A laptop takes ages to boot up let a lone the loading of the email client.
The main reason I got an Ipad was because I LOVE to read the paper outside, but the wind blowing the paper around drives me nuts, the Ipad is a killer in this regard.

I have an Asus EP121, 4Gb ram, SSD drive, etc. It takes 20 seconds to start from cold onto the desktop. Anotgher 2 seconds to pen my email application.Is that fast enough?
from sleep, we're talking seconds
