In my experience, I've found it easier to simply carry the Apple wireless keyboard around with my iPad. It's easy to just toss into a bag. That way, it doesn't add bulk to the iPad itself, it's optional when you want to use the iPad for gaming, reading or surfing, and I'm not worried about it's longevity. Not to mention, it's about half as expensive.
I'm not particularly fond of Clamcase as a company, either. They seem to be a little shady/uneducated in some respects. For example, when everyone was waiting for their cases to ship (after multiple delays), Clamcase wasn't forthcoming with information at all. They would give fake tracking numbers and ship date estimates, and when the forum on their Facebook page got overrun with irate customers, they simply shut it down (and then said it was a "mistake" when websites like Engadget picked up on it).
