My Apire is the 4520. It has less memory than some of others but I didn't need too much. My Acer did come with Vista but like adamsmith, I got used to it.
Babala and I have the same model.
For an extra 200RMB (or less) you can juice the thing to 3GB (4GB of RAM or more is beyond XP's exploitability, but if you go Vista it recognizes the full 4 and more. I won't go Vista, so the 3GB is acceptable on this laptop) and not dramatically over clock the processor. Add the cooling pad , which is basically a few fans, and you're good to go.
It is AMD Turion 64 X2 2GHz, came with 1 gig of RAM but I'm running it on 3GB of RAM, and it has four usb, an S-Video jack, one dial up jack, one dsl jack, a firewire jack, VGA jack, a SD memory slot, and NVIDIA GeForce 8400m G 128mb on board graphics.
It's a cut-and-run puppy for my home theater on-the-go needs, so you could go for one of their other models for HD support or serious gamer needs must be met, etc. You might have to if you want wireless ethernet capabilities. It has bluetooth, but I've never used it.
Really, the greatest thing about computer shopping in China is that you can work around things easily, such as getting that fly laptop that has fuck all RAM* by simply buying at the deal price and then having the shop flunkees soup it to the max - far below what the same thing would cost at sticker price with the amount of RAM you really want, but ended up putting in it anyway after the fact.
If you go for one of the newer, more frilly models you can still upgrade ram and the hard drive without fucking up the works and still do the same thing.
* a far too common practice, here in China
