You missed the best laptop of all. And it's because you were looking for laptops.
The HP tx2500 series is considered a tablet, with swivel touch screen. I have the previous generation, the tx1000 series, and I love it. They're 12.1" screens, have great battery life, have a non-intel graphics chip. Mine has a geforce go 6150, and it does light gaming fairly well. Best part is, you can find htem for $750-1000, very cheap for what you get.

The 2500 series seems to have the Radeon HD 3200 graphics chip. My laptop is exactly one year old, I bought it january of last year, and it's holding up great. Super durable, doesn't feel flimsey at all. The dvd burner has litescribe, so you can burn your dvd lables as well. I don't use the tablet features of my laptop, but i wanted like you want, small, super portable, and great battery life.
Hope this helps a bit.
