HD (1366 x768) or better resolution with that resolution not being fixed. That is it can be configurable to say 1024 x680
Ah I see. Well, all graphics cards allow for changeable resolution, so that should not be a problem. the 1366x768 resolution is more commonly found on laptops that are slightly larger than netbook sized ones (13" or 14"), so i'm not sure if that'll fall under your definition of a netbook anymore.
Also, it is somewhat hard to find laptops with linux pre-loaded, so you might have to install that yourself, over the shipped Windows XP/7.
Also I think there might be a unit out there with the Nvidio ION II GPU
Currently, the only ion II equiped netbook is an asus 12" one (the Eee PC 1201PN).
A 10" ion equiped netbook doesn't exist.
If you're willing to forgo the ion 2, but must have the resolution, then you can try the 11" sony vaio X series, which only weighs 1.6 lbs, and still has 1366 x 768... but then the price you're paying is ridiculously expensive ($1200 or so).
Alternatively, you can try the vaio P series, at 1.3 lbs and 1600 x 768 resolution, though the screen is only 8", and costs around $900.
There's also the first generation HP netbook that i forgot the name of, which has a high res screen as well, but since HP already put out a second generation of the same thing with a lower res screen, i'm not sure if the first gen version is still being sold anymore.
OK thanks all - here i thought there would be a magical place where my ideal machine would be custom built - or at lease a customizable skeleton would be available.
I think I am off to buy what i can and make what i want.
