The Apple iPad 2 Review
by Brian Klug, Anand Lal Shimpi & Vivek Gowri on March 19, 2011 8:01 PM ESTHDMI Mirroring
With the iPad we complained that the A4 didn't seem to include any form of digital video output, only analog outputs were supported. The A5 and the iPad 2 both rectify that as Apple now offers a $39 Apple Digital AV adapter that gives you HDMI out directly from the iPad 2.
The Digital AV adapter is a bit clunky and I believe the future of this is clearly in some form of wireless transmission, but for now it plugs directly into the dock connector. Apple had the foresight to build in a second dock connector into the dongle so you can keep your iPad 2 charged while you're mirroring it's display.
With the adapter connected HDMI mirroring just works as you'd expect it to. There's no setting you have to enable, just plug it in to your display and you're good to go. The iPad desktop is upscaled to either fit your display or it'll appear as a box in the center of your panel.
I tried the AV adapter with three different displays: a 720p Pioneer plasma, a 1080p Samung LCD and a 1920 x 1200 Dell PC monitor. With the 720p and 1080p displays I got an upscaled box in the center of the screen
On the 1920 x 1200 Dell panel I got an upscaled image that took up the total height of the screen:
In all cases Apple maintains aspect ratio.
What about functionality? Everything you see on your iPad you see via the HDMI output. If the keyboard appears on your iPad it'll appear on your HDMI display. Personally, I would like to be able to have the iOS keyboard visible on the iPad 2 but not on the image sent over HDMI. Currently it's a pure clone setup...mostly.
If you try to play video while connected to an HDMI you won't get a mirror instead you'll see the video full screen on the external display. This is true for Apple's own video player app as well as 3rd party apps like Netflix. Note that while playing a video you will only see it on the external display, not both.
Audio is passed exclusively via HDMI as well, the internal speaker is shut off.
Battery life takes a significant hit with the HDMI output enabled. While you'll see that our typical usage tests can easily hit 10 hours, over HDMI you can expect battery life closer to 8 hours. It's still not bad but definitely a larger impact than I expected.
HDMI mirroring on the LG Optimus 2X
HDMI mirroring isn't exclusive to Apple, we first saw it appear on LG's Optimus 2X and later on other Tegra 2 devices. While HDMI mirroring turns your iPad into a portable Netflix machine, it also turns it into a semi-dockable PC. The limitations I mentioned earlier still exist. There's no mouse support and multitasking is a pain compared to a full blown PC, but this is just the first step. If all you've got a light usage model and just want a more ergonomic setup at your desk, there's no reason you can't connect to a standard HDMI display and use the iPad 2 as a glorified keyboard/pointing device.
What I would like to see going forward is support for some sort of a pointing cursor within iOS while connected via HDMI - only on the external screen. The same white circle that's used in Apple's demos would work just fine here.
The question I have to ask is whether tablets based on smartphone hardware and OSes are going to become powerful enough to double as portable PCs or are desktop OSes going to become lightweight and efficient enough to run on smartphone class tablet hardware? The latter seems to be Microsoft's strategy with Windows 8. Unify the software and allow it to run on all platforms, while the former is where Apple is presently headed with the iPad. It's clear to me that convergence between desktop and ultra mobile OSes will happen at some point, I'm just unsure which side will lead the merger.
Charging
The iPad 2 uses the same 10W USB wall charger in combination with a 30-pin dock-to-USB cable as the original iPad. The benefit here is any iPad/iPod/iPhone 30-pin dock cable will charge the device (assuming your USB port properly implements the battery charging spec). On the flip side, even with the 10W wall charger you're looking at ~ 4.5 hours to get a full charge on the device. Charging via the PC is even slower - it'll progress at roughly half the rate as you can get via the wall charger. Note that like the original iPad you'll need a USB port that implements the battery charging specification in order to charge from your PC/Mac. All of the new Mac notebooks seem to implement this spec (2010 MacBook Pro, 2011 MacBook Pro, 2010 MacBook Air) and had no problems charging the iPad 2.
The Xoom by comparison avoids this problem. The USB port on the Xoom is only used for syncing, there's a separate dedicated port for the wall charger. As a result you'll get a full charge on the Xoom in 3 hours.

I have to agree, the 11" MBA is one extremely sexy piece of kit.I wish there was a similar option that wasn't branded with the half-eaten fruit of hipsterdom. And doesn't run OSX, which I don't particularly like.

iPad does have for real 10 hour battery life and is generally maintenance free. Charge it, pick it up, use it. But, the Air gets a solid 5 hours (gets me from coast to coast) and is also pretty much instant on and generates no heat and I never hear the fan. So, although the iPad has a clear advantage in battery life it has no clear advantage as a "consumption device" and it forces you to favor apps and it does not handle media files as well and it does not have flash, which, is still out there.As far as price, yeah, the 11" Air is 50% to 100% more expensive, but ULV Sandy Bridge will see a flood of products on the PC side of things that should have lower price tags and if some PC manufacturer would please step up and start taking product design seriously.
I typed this on my Air, and I would probably type less and put less thought into it (the same dreaded way that BlackBerry effect has really been a setback for written communications with the half butt answers) on an iPad.
Also, one last Air advantage, it has a screen on a hinge. I got so sick of hold the iPad or having to prop it up on things...
The iPad is a +1 device, sure, but... I'm going to stick with the 2 pound laptops for a while.

Well, if I deserve to be called a hipster or dickhead by some poorly educated idiot with two brain cells (both of them obviously white) for owning an iPad along with a MacBook Air, Mac Mini Server, MacBook Pro 15 and 17", 27" Cinema Display, iPhone4 and something else I forgot, then so be it. I'm not offended in the knowledge who the comment came from. A really sad case. Can't help feeling sorry for you, Kuka-whatever-your-screen-name-was.It looks like the comments here have been written by people under the age of 45-50 because no one has ever mentioned glasses. Yes, those things people need to see what's in front of them, far and near. It's worse when you need both. Then you won't be so happy to do any kind of work on an iPhone or even surf the web. You would wish for a larger screen every time you are forced to switch from your normal glasses to your reading spectacles. Use a netbook? Even worse. A tablet is different and allows you to read with your nose practically replacing your fingers on that touch screen. Perfect!
As a surgeon, I often have to show other people what I mean. This can be a scan, a plain radiograph, lab results and so on. Unless I have a big screen right there for all to see, the iPad is the gadget of choice. Give it to the team before surgery to look at scans with my notes right there on the screen, pass it around when on teaching rounds, give it to a frightened patient to reassure. Try doing the same with a smartphone or a netbook (useless toys that they are) and you will see how crazy that idea is.
Basically, in my field, there is no end to the list of possible applications. This is combining consumption with creation. Therefore, before using such terms as dickheads, try to think a bit further than your own little world if your "processor" has that much power. If not, well... As I said, a very sad case.

Thank you. I wish more folks would pipe in with the real-world capabilities and uses they're discovering. No matter though. Apple-hate isn't new. I dealt with it in the '90s when Apple really was in trouble. Apple currently firing on all cylinders just keeps giving haters more and more to bitch about. (Price of success perhaps?)Hipsters? Dickheads? WTF?
This comment isn't about the review but the inane comments that invariably get trotted out by hater technogeeks that won't move out of their mother's basement, disappointed that all the flash-porn won't work on an iOS device. Instant "fail" (or whatever silly phrase the self-annointed, self-important digerati are using today) in their book. These folks need to get out and learn that most people are "not" like them. But that would require getting a life. (Which would probably be easier than getting a date...)
(See? I can paint with the broad strokes too. ;)

I just wanted to say that I really enjoyed Alexander's glass article, it was a great read.My grandfather was a material scientist, so it brought back a lot of good memories.

Thanks for the great review. Anandtech seems to be the best site for independent and in-depth reviews. Please keep that going, because there is too much fanboyism going around. Saying that I have to admit, that I lean towards the Android side, because I think it's much more suited towards the tech enthusiast. Right one my HD2 is running the newest Gingerbread 2.3.3 rom from XDA, something impossible with iOS. However, I'm typing this on my iPad and if you would ask me which tablet I would recommend to my parents right now, I would say the iPad.I myself will switch. The question is if I can hold out to the quad core SOC that have been announced for later this year or will go for a Xoom wifi only model. The iPad convinced me that a tablet is what I need most of the time. However, iOS is hopelessly outdated. No widgets, notifications are laughable and browsing is annoying. With no memory, switching between tabs means reloading almost every time. And loading is slow.
That's also why I was so interested in your browser scores. Couple of things I noticed. First of all you switched back to manual measurements for the page loading, because the Honeycomb browser stopped the timer too early. Isn't that just a sign that it is fast or was it really, really early? Manual measurement has it's on flaws though.Very susceptible to operator bias. I don't think you should report your scores in milliseconds then, because that implies an accuracy you just don't have. Furthermore, I would like to see error bars, so we can determine if these differences were really significant.
Again, these are my comments. Thanks for the good work.

want it on android...TEAMSWITCHER - Sunday, March 20, 2011 - link
I purchased an iPad 2 for my wife. I had been giving her my old MacBook Pro laptops, which at even four years old are complete overkill for her use. She adores the new iPad. It's far more portable and can be used in more situations than a laptop.Case in point, this week she created the family shopping list on her iPad 2 and brought it grocery store. She browses the WEB, FaceBook, games, EMAIL, and keep all her favorite photos, movies, and music.
From now on, i'll be hocking my used MacBooks on craigslist if I can. She doesn't even want a laptop anymore. That's the biggest issue I have - it's too good. Too many people will find that tablets are better and abandon their laptops altogether. Laptops will stop evolving, much like desktops did once Laptops became popular.

I agree that it's a better laptop for casual users. However the Flash limitation I believe is still a problem that prevents it from being a complete laptop replacement for even casual users (a lot of restaurant, automotive and photography websites are still unfortunately 100% flash based). As long as you have some access to a laptop however this is really a non-issue, except when traveling with only the iPad.Take care,
Anand

I enjoyed reading the review,but it seemed a bit biased to me. While it's true that the iPad can't replace a laptop for content creation it works just fine in many fields. I sell annuities and the iPad has totally replaced my laptop when I'm on the go. I have designed presentations using keynote before and It worked great, whenever meeting a client I always bring my iPad instead of carrying paper brouchoures, in fact most of these clients end up getting an iPad themselves after playing with mine. Maybe Apple should pay me for advertising their product.
