This is what I'm going to do with Neo900 *if* it ends up with having some kind of scale-less video output (VGA, DVI, whatever). If not, this is what I'm going to do with Pyra instead of Neo900, as it's going to have this feature for sure

Although, I must say, that I still see powerful, regular-size desktop computers as part of this "idea". Desktop computer with replaceable parts (and better performance/price ratio) for in home entertainment/work, and mobile device for all other (and the same on-the-go) needs (that can connect to big screen, keyboard, mouse etc, if need to emulate desktop arise). Not to mention that this mobile device can still connect to desktop via ssh, vnc, or x-forwarding, if need for max performance of calculating something arise.
