[citation][nom]phatboe[/nom]Please don't compare Surface to Nexus tablets. Surface is a ~$500(ARM) ~$1200(x86) tablet while the Nexus is a ~$200 tablet (all prices estimated). These tablets have different target audiences and will not directly compete with one another.[/citation]
I'm guessing Surface will be closer to $599/$999. Ultrabooks were listed as a price comparison for the Pro model, and by a rule they have to start at less than $1k.
Still, I've been planning to buy a laptop or tablet later this year, and Surface looks like it will fit the bill of what I want very nicely. I'll gladly shell out $1k for it if it performs half as well as I expect it to (seriously, it's Ivy Bridge, that thing is going to scream).
