More then a PDA but not a full Tablet... It's not available yet, but said to be coming soon.
I could easily see this as the future for mobile computing. Yes, hardware will cost more, but you won’t need a PDA and a Real Computer. “Just this thing” (a real computer). And you doc it with a full size monitor and keyboard when not mobile. Lacks some ram and high end video card, but it will get there.
