I really want to make my own tablet PC like iPad, HP Slate, Motorola Xoom etc.
What components would you recommend? It will probably have 512MB ram, and run Windows XP.

Well, first you're gonna want a touchscreen. Look into how big it is IN THREE DIMENSIONS, how heavy it is, and the quality of the build. Then, you're going to need to select the internals. Now, the first thing that would jump to your mind is the latest processor from Intel or AMD. That's bad. You're dealing with what is in effect a small laptop: the heftier the processor, the more cooling and power will be needed. In something that small, you can't deal with either. Go with something based off of the ARM architecture. Although this architecture isn't very powerful by nature, it's the only way to get any battery out of it at all. A bigger problem with it is that no version of Windows supports ARM. You'll have to use Linux. But it'll be well worth it because you get a battery life that isn't measured in seconds and you'll save a LOT of weight and space with the lesser cooling ARM requires of you.
Now, for the internals. You will have to recycle an older circuit board and solder in the processor, or you could create your own, solder the ARM chip in, and write new device drivers for it in Linux. Note that by Linux's nature, even though no-one else will be using your unique board, you still have to submit the change as a patch to Linux kernel developers. Because there will not be enough room for conventional DIMMs of RAM, you'll have to solder in individual 'packets' (as I like to call them), or chips in which data is stored. Next, a video card. Integrate a small, low-power card into your board. Once you've done that, find a small battery that can 1. fit in your case, and 2. carry enough of a charge to get you through a day. This will be pretty pricey. Acquire a method of cooling for the ARM chip discussed previously, and implement it. Next, you're going to need block storage. You'll need an SSD. Try to find one that fits with your form factor: preferably, 1.8" or less. Now, put all of it together, install Linux, and voilÃ¡. Your tablet is complete.
Now, all of this was pretty hard, you probably spent much more money than you meant to, there's no guarantee of success, and after you're done, the result isn't even that impressive in terms of tablet computers. That iPad's looking a lot more appealing now, isn't it?
