TouchFire: The Screen-Top Keyboard for iPad
This looks like a very promising product. A thin rubber overlay for your iPad that provides tactile feedback as you type. Held on by magnets, and works with both iPad 1 and 2.
I always thought carrying around a separate keyboard somewhat defeats the portability of the iPad. I have tried the clamcase in the past, but stopped using it as it makes the iPad too bulky. If anyone types a lot on their iPad, they should check into this product. It's a Kickstarter product, so not yet available, but I have no doubt it will come to market.
