Just got an Otterbox for the iPad...

I've used the Defender for the iPhone (too bulky), and switched to the Commuter for my 3GS, then for the 4. I've seen the Otterbox for the iPad and personally, I think it is too bulky. A friend had a difficult time slipping her iPad into the case, then gave up after a few weeks. If you toss it around, etc, it is worth it, but I'll stay with the Apple iPad case for now.
