Unfortunately, Android is a terrible OS for a tablet. I would much prefer some sort of Linux distro, like MEEGO, over Android. Blackberry Playbook looks like a winner too. iPads are awesome though. It will be a tough fight. I just don't see Android tablets coming out on top when everyone who knows the OS knows that it was made strictly for phones and they are just now starting to adapt it to tablets.
