With 7, "full blown" is a matter of discussion, because W7 scales back depending on the machine. When I saw the behemoth allocate 2 GB just to breathe I thought that was it. Yet, it runs on a dual core atom like a charm, with half-a-gig of RAM. It chews of its own legs to fit in, rennounces eye candy, scales back of buffers, etc. It fits where XP used to.

I'm not saying I want W7 on my phone (this phone), but it's not quite as bad - hence the W8 unification. If I had a dual core 1 GHz Atom and 512 RAM I'd give it a spin.
