The original OLPC is a good piece of hardware, but i don't think the plans for the OLPC 2 are the best way to go, even with energy efficient displays, having two of them just increases power demands while not adding that much actual functionality (more of a gimmick). Instead I think it would be better to use a single, larger display, maybe get Pixel Qi to make some 11.6" displays with 1366 x 768 full colour resolution, surely this would cost less than two displays while making it possible to comfortably run any application imaginable (say GIMP). Secondly, I think the processor is a poor choice, it would be better to have a good ARM processor (Snapdragon?) instead of a crippled x86, and probably for lower cost too. Otherwise, it would be good to keep the rest of the original OLPC in terms of spec, tablet is the best all-round form factor, although moving the speakers, controls, cam and mic to make place for the larger screen would be necessary. Well that was my $0.02, hope some of this gets through to the devs.
