I'm thinking about it, how is 7" compared to 10" for a tablet? I have a Galaxy Nexus already with Jelly Bean but I've always wanted a tablet device for casual browsing or film watching. My GN does this to some degree, so I'm not sure how useful a tablet would be.
I find movies in letterboxed mode are a little too small to watch. If you stretch them up they are more watchable, but you'll lose a little bit on the sides obviously. For serious movie watching, it would probably be better to have a larger screen for the letterboxed version.
