I'm in the market for a 10" Android tablet, but not sure which is the right one for me. I'm looking into the Transformer Prime (a friend is selling his)/Infinity and the Galaxy Note 10.1 at the moment. My top 5 most important criteria are: 1) Screen 2) Expandable memory slot 3) Actual performance (although I don't game much on tablet let alone with my iPhone) 4) Decent camera 5) HDMI out (can live without it) I'm curious about GPS, and that probably means the Nexus 10 is in the list too. Is it a A-GPS unit? Thanks for your input.
