IPad 2 Teardown Shows Tablet's Guts
alphadogg writes "Apple's iPad 2 tablet, which became available Friday, boasts a big battery, tiny speakers, an ample 512MB of RAM and a glass front that's tricky for tinkerers to take off. That's the upshot from an initial teardown of the new Apple tablet by iFixit, which specializes in Apple product repair. IFixit warns that those who dare to peer into the insides of the iPad 2 on their own risk cracking the glass front panel, which is thinner than that from the original iPad (0.62 mm vs. 0.85 mm) and glued on rather than attached via tabs. A heat gun was needed by iFixit to disassemble the device."
I don't really like the normal tablet style of iPad. I mean, it works I guess, but people are more used to holding books. I got interested in tablets after I saw Microsoft's Courier, but it looks like they cancelled it.
Is there any other more natural feeling tablet? It would be much better than the usual ones. Since all the Android devices are quite much clones of each other, I hope someone uses this to their advantage and makes a device like Courier. Or Microsoft should continue their project. It's really interesting anyway.
This is not a fucking hobby project. This is a retail device, sold for profit. You are NOT encouraged to take it apart. This entitlement attitude of being able to reverse engineer everyone elses IP is starting to piss me off.
Sounds a lot like an iPhone 4 and the Macbook Air. I work for an authorized Mac sales and service center; our Mac specialist had to use a heat gun to take the screen/glass off on a Macbook Air. Research for the iPhone 4 returns similar needs.
Like the article says, a heatgun did the trick.
Have you ever seen somebody watching a two hour movie on ipad? It's a sight to behold. TWO HOURS of holding it in your one hand.
Also, did they find any keyboard in the 'guts'? I guess not. I have tried my hands on this newfangled touchscreen keyboards, and boy, do they suck.
The point I am making here is - tablets do not function as a useful tool except for the guys who scan your creditcards with a handholding device (and for similar purpose). But who am I to reason with retards, fucktards and fanbois?

and their review helps as well http://www.anandtech.com/show/4215/apple-ipad-2-benchmarked-dualcore-cortex-a9-powervr-sgx-543mp2
The key items to take away from both are, yeah the cameras suck but this is truly a real upgrade from the iPad. Performance alone puts is ahead of the older model as well as many available tablets. They did find out that the dual core processor is actually running at only 900mhz. While the Xoom pushes more pixels because of its 1280x800 versus 1078x768 the iPad2 pulls far ahead of it, beyond what the pixel count would account for. As for gaming, some games are already taking advantage of the new power, Infinity Blade has been updated and looks fantastic. This brings up the issue, will there be apps sold that are marked iPad2 required?
Better yet, its cheaper than its nearest competition. The only question is, how long before really good Android tablets come along?

"ample 512MB of RAM"??
Realy?
Boy. THAT was a lame article. It was, word for word (except where they doubled up on the same sentence twice) everything stated in the iFixit video. This guy must a spent a LOT of time copying off other people's tests.

Why the main article this summary is about is not linked is beyond me...

so this is why ipad2 is so cheap. tiny 512mb ram. and shitty cameras. no wonder samsung is finding it difficult to compete with its 1gb ram tablet with a 2mp front cam and an 8mp rear cam, 1080p recording, dual core graphics, dual core cpu.
only steve jobs suck-ups can call 512mb ample.
Wealth is the gift that keeps on giving.
Sorry to burst your applesauce bubble, but 512mb ram is hardly ample in 2011.
Truth mod me up, fanboy mod me down. In the end, you know an expensive piece of tech like this should have at least double, if not quadruple that ram... its 2011, don't forget that.
...and copy the sleek design to create a product that is equally appealing to the eyes and twice or three times as powerful?
And they're asking several hundred dollars for it? How stupid can people get?
certainly makes the case for having a full tear (fall) down? what do they intend to prove? just what do they intend at all? gut staring? what's that all about?
I started counting a couple of stories back, this is the sixth first post defending Microsoft that devxo has posted in the last three days.
The other five are:
1
2
3
4
5
Liking Microsoft products is one thing, but keeping tabs of every story and writing a multi-line first post for every other one, well that looks like a real job to me. I wonder how much Microsoft pays him. Does he get overtime, considering all this was done in a weekend?

once their guts (or any other part) are severed (by mortar rounds (get used to saying that?)), everything comes out at once. sometimes, the mommys are unable to die on the same spot, although it would be their preference, & are instead captured, tortured etc.... they do tend to try to stare at what's left of their babys as they're hauled away/dying themselves. it's almost never 'quick' (like on tv) either. see you after that stops.
Does it make it harder to repair...yes. Do modern devices like this need as much repair (I bet the p(95) MTTF is incredibly high)...no.

What does it matter what method is used for structural support - screws or glue? As long as the glued components can be removed for servicing without causing cosmetic or functional damage, then why not? And as for using a heat gun, that makes sense (again, as long as no cosmetic damage is made in the process) considering you can't use tabs or screwdrivers on glue very easily. My concern would be the usage of this glue in devices that may be used by people living in high-temperature environments. I live in Australia, and normally temperatures can get quite high here in summer. Now, the operating specifications have a maximum operating temperature, but the equipment can be protected by keeping it off in the hot time of the day when outside, but that won't protect the glue from losing structural support.
I've already told one potential tablet adopter to wait for the Xoom, because it's already known that it is very serviceable. This means that in-house IT will be able to cannibalise machines for spares after a year or two, and replace the batteries, without having to send things off for increasingly expensive repairs. The Xoom seems to be designed much more with corporate IT in mind. I know that the iPad 2 is thin and light, must have gadget and the rest of it, but corporate users have other priorities.

"As others have pointed out, Apple really doesn't make any profit from the iTunes business, they just make it available as an inducement to buying iThings"
Apple grossed $4B from iTMS in 2009. Its impossible they didn't profit from this revenue.
The Xoom compares to only one iPad2 model, a 3G unit with a decent amount of storage - and even then it's around $70 more.
The thing is that you can get twice the storage for even less with an iPad if you are willing to forgo 3G. Or if you don't have a lot of money you can get an iPad for many hundreds less.
I don't think it's correct to say that because one particular model is close at all price-wise, that the two units are close in price. You have to consider the entry price to get into the platform, which is the starting point that consumers use to make choices. For someone initially considering these two devices they come off as $500 for an iPad2 and $800 for a Xoom... or even to be fair I guess you could use the subsidized Xoom price at $600. But that seems a bit dubious to me as not many people will see that price and it's not MSRP.

I don't know how much more efficient Dalvik may be than standard JVM, but it is silly to try to equate the two operating systems' resource requirements. iOS runs native C (Obj-C/C++) code without garbage collection, so it's about as close to the metal as can be. The Java VM is without question slower and has more memory overhead, and garbage collection is one part of the reason. I've always joked that with Windows you lose one CPU core to your anti-virus software. With the JVM, you lose some of your CPU to garbage collection, and there is definitely memory overhead. The VM does not come for free -- in order to avoid problems on servers with periodic long garbage collection pauses (app lockups), one solution is the concurrent mark-and-sweep collector, which basically takes a certain amount of CPU overhead all the time as the tradeoff. I *love* Java, but there is no denying that it is noticeably slower than native. JIT etc. fix most of this in theory, but *not* in practice.
So for all you know, Dalvik apps eat twice the memory and twice the CPU, explaining why the iPad could have half the memory and CPU cores, and still be just as fast. If you don't have concrete numbers in those areas, your complaints about "iPad not enough memory" are just pulled out of thin air.

Stellar job as usual, editors, allowing someone to post a shitty blog link instead of the real article.
Also, you and your GP are doing the traditional US-centric thing of thinking that the US model of highly Taylorised corporates applies everywhere in the world. In the UK (and Europe) there are many SMEs (i.e. up to around $500 million turnover) that do not fit the US model, and the company I referenced is one of these. My company works (among others) with outsourcers and with break/fix companies that supply services to these SMEs, and I can assure you that maintainability is important to them. Traditionally in costing laptops and similar equipment they factor in an oversupply to deal with EOL maintenance and field failures once the manufacturer warranty expires. Maintainable equipment equates to a lower oversupply.
But shoot, what do I know? I've only been in the business eleven years...whereas I guess that someone who has to SHOUT a lot to try to make their point is probably under 25.

Digital distribution is -cheap- REALLY cheap. Doesn't cost much to host data and send it over the net. For example Netflix pays about 5 cents to Akamai to stream an HD movie. That's 3GB or so of data and remember: Akamai does the hosting as well as the bandwidth, and they have to make money on the whole deal too. So, when you are talking music, small apps, and so on you don't need a whole lot of money to cover costs. Even when people download multiple times, you are still talking fractions of a cent it costs you.
You want to see some evidence that digital distribution makes tons? Look no further than Steam. Here you have Valve, a private company, so no big investors to prop them up if they lose a ton. What's more they've got no consumer electronics division. They do two things: Games and digital distribution.
Well Steam makes them bank. They are more profitable than ever and indeed don't have to worry about game release schedules because Steam is where their big money is. Of course the downloads on Steam are large too. Normal games are 5-20GB these days. What's more, they give away bandwidth. If a game uses their Steamworks copyprotection, then any copy purchased registers on Steam and is eligible to be downloaded. However they don't charge for it. So while they take a cut of the sale price if you buy it on Steam, if you buy it at Target and then register it, they don't. None the less they still provide you updates, reinstalls, etc from Steam to your heart's content. Of course there are other free things too. Demos, no cost mods, videos, and so on.
All that and they are raking in the dough.
So I'm sorry, but I'm not buying Apple's "Really we don't make any money on iTunes!" crap. Yes they do, plenty. Perhaps I could buy they don't make much on the music part, since the music industry probably fucks them on fees, but even then I'm skeptical. However software, apps? Hell no, they make bank.
I happen to love demoscene stuff, but I also happen to have a realistic assessment of what it is and how it works. So, let's take a look at one of Farbrausch's demos, since they really are the kings of the 64k compo. So we'll take fr-27, it's one that after the contest they managed to optimize down to just 47k on disk. All that and ti is full 3D, amazing. Ok but here's a question: How large is it in RAM? Answer is 77MB. That's right, as it loads (the little white bar on black background) it is generating a bunch of procedural data to RAM. Tiny on disk, big on the RAM.
Also all it manages with that is some very simplistic geometric shapes and animations. It's cool, don't get me wrong, but it is just very simple stuff. No complex artwork, no detailed animation.
So let's take a newer one, fr-41. This one is a little larger but still only 177k on disk. Also it has a full city scape that is quite nice looking. Still suffers a bit from the procedural generation "copy-paste) brush, but is far more than just simple geometric stuff. Also has some more advanced animation and morphing. Plus it has a UI to configure things. So how's it do on the RAM usage? 835MB. Damn. It has to decompress a ton of stuff in to RAM to fit in that size.
See those small demos are the art of a certain kind of optimization. You go for low disk usage at all costs. That's fine but it ends up taking up massive amounts of memory, plus heavy CPU and/or GPU usage to generate the content. Fine and extremely cool, I -love- it but don't pretend that all programs could be like that. Also it couldn't run on the iPad, not near enough resources.
Then there's just the fact that you lose flexibility. You have to deal with more simple things when it is all procedurally generated, you lose artistic control. You can see it in Farbrausch demos. Have a look at fr-25, their second most famous one (fr-19 their fist 64k is their most famous). It is a demo with a fully produced song with vocals and instruments, not just algorithmically synthesized music, and with advanced animation. Uses the same engine as their 64k demos, but weighs in at 8.6MB.
So you might want to learn a bit more about the tradeoffs one has to make for some of these things. To briefly touch on your garage band thing, I have multiple General MIDI instrument sample libraries. My smallest is a 4MB SoundFont. My largest is 40GB. the 4MB and 40GB library span the same collection of 128 instruments. However if you think the final sound is the same, you are kidding yourself, I don't keep the big one around for show.
