I 1000% agree on releasing with the Atom processor, this is what allows MS to compete with the ipad pound for pound in EVERY category, with the exception of having a real OS. MS left this category to the OEMs, who fubared it by not having anything ready for release. I'm very surprised MS isn't releasing an Atom surface.
Windows 8 isn't that bad. If you look at the desktop side by itself there were many improvements under the hood, certainly enough to justify $40 upgrade. Metro does suck though, but you aren't really forced to use it and it will be the key to the future if MS can improve it.
I personally think the Atom should have gone into the Surface RT and not even had RT at all. That being said I still like my RT
However for the Pro I would rather have an i5 over the Atom. The current high end Atoms lack in memory capacity and GPU prowess.
Laugh while you can, one of things that I will enjoy about the Surface Pro is the capacity for "Vidya" games. I already run a similar specced laptop with last gens i5 and Intel HD 3000 and it pumps out some decent 720p gameplay for my current library of games. Also the programs I use for work have higher CPU, GPU and Memory Cap requirements than what the current gen Atoms can provide.
