i just bought an HP TX1340EA, VERY similar. twisty screen (of dubious benefit), touch screen (which has a weird slightly silvery sheen to it, which messes up colour representation a bit), but is a nice little box, for £700, considerably less than this, admittedly nice looking box.
windows was originally written on compaq hardware, so it always used to run best on it, tho what actually runs at all on vista is up for debate, atm! (probs with SP1, already!)
i always found the compaq brand to be usually better, stronger build.
i love these new tiny laptops'. imo it's what laptops should always have been, not vying for desktop business!
btw, i'm collecting stories about baby laptops:
if anyone has any others they think should be considered, you're welcome to let me know or post there ;)
