Funny people are still negative about the Atom. I mean, yes they have a poor image in the PC space, but heck, this is a tablet we're talking about. Plus Medfield will share the SB/IB architecture which has huge IPC performance, which is what you need for the mobile space, not "more COARS!!".
I'm not saying it'll blow ARM out of the water, nor am i trying to be a fanboy, i'm just saying, give it a chance. Competition is good, after all, and Intel can't demand the same prices when it's the one competing.
