Query: This keyboard is a great idea, but has some problems.

I bought this keyboard in hopes of turning a PDA into a laptop without all the hassles and size. The problem is that this keyboard is hard to open and the keys stick sometimes. Not to mention, I have big fingers and the keys are too small to punch. So think about these problems before you purchase this keyboard. It earned two stars in hopes that Palm will improve this product.
