Well, this is the first non-iPad tablet that I find remotely compelling. If this thing doesn't require a carrier to be useful and affordable then it has a chance.
I'd be willing to bet that it won't pair with non-blackberry's (although maybe they'll surprise me), but if you have a BB (like a large number of people do) this should be a good companion device.
As to price, they didn't mention that or availability; which I suspect is bad news on both fronts. They're really pitching this to enterprises, so I'm guessing affordability isn't their primary bullet point.

It should be coming out in a few weeks, so it should be one of the first decent iPad competitors.
