Wish they would, I started using AIV to get new shows without downloading. Partly since usenet indexing was sketchy for a while, but it's also convenient and cheap, and since I'm in the states now I can actually get content.
Very glad these are finally out. Not sure I can justify to myself getting the 8.9 (have a nexus), but maybe a 7". I really do love the screen on the 8.9 though.
Makes perfect sense since they have Amazon Instant Video.
