when it comes to gadgets like these my mind is always made up by asking myself the question... "is the manufacturer going to support it? and if not, what are the chances of it being supported by a developer community instead?"...
in this case i'd end up going for the touchpad... there are some very talented individuals working toward getting CM7 running on it. it's already a nice tab but it's going to get awesome in the coming weeks.
