I'd say Courier works hella better as a piece of software than hardware.
I'm sure that's no secrets, and why Courier got killed as a hardware project. Can you imagine MS sinking millions into a uni-tasker like the Courier, when a small software company can copy the concept and put it on a tablet?
People got so POd cuz it got killed, but that's absolutely the right call 100%
I agree with you, I think the courrier project is a good software one and I don't think I would want to have yet another piece of harware with me all day. Nevertheless, I think that good software needs good hardware to run smoothly and I think there is no good hardware for Windows slates at the moment.
