I keep being surprised that there is no real ARM netbook (samsung's chromebook and asus transformer come closest). I think the reason is because ARM is significantly less performant than x86. You don't notice it on a phone/tablet, because the stack is optimised (it has to be!) the special-purpose OS, lots of stuff in silicon (esp video), games and (mobile) webpages are written for the platform. But for general computation - e.g. compiling - it's much slower. ARM has optimised power consumption for decades; x86 has optimised performance for decades, so I shouldn't be surprised. PS: doesn't ubuntu have an ARM laptop in the works? (along the lines of their EDGE phone)?
