This tablet (and the keyboard dock) has my highly interested, I was originally waiting for a 7" tablet but the keyboard dock just makes it much more attractive and can replace my netbook while on the road. My netbook barely lasts 2.5 hours on a full charge, with the Asus Transformer and the keyboard dock it should be 16 hours!
As poorly as the Xoom sales has been according to reports, it'll do even poorer with lots of returns for this tablet. I know the Xoom is 32GB and this is 16GB but with the microSD slot, why need any more than 16GB? If the Motorola released a 16GB Xoom, it most likely would've still been $499.
