We used this case for the iPad 2, and are now using it on the iPad 3. It was actually a bit loose on the 2, but fits the 3 perfectly.
I know exactly what you mean about the sharpness of the edges -- but with this case, the feel is perfect in my hands.
We tried this case, too. It's very good, but the feel is a bit more "rougher" than the radtech case. It's by no means a deal-breaker, but we just prefer the radtech. In terms of construction quality, both are excellent cases.
To clarify, the radtech is closer in feel to belkin grip vue. Incipio's case is a bit more rugged in feel.
