"""Why not focus on smaller die mobile duo core run at 1.0 ghz neighbor with mere 1.5 W power?"""

Why don't we all just focus on 64 core mobile, small die chips that run 30GHz at 16 pico watts? Sounds better than the imaginary chip that you're on about.

And those Geode chips are kinda large, although they don't even require a heatsink, which is pretty excellent.

And I seriously don't see the point of a dual core on a umpc - waste that die space on cache, performance optimizations, or a memory controller.
