I'm thinking about a tablet (you may have seen me annoying people in the iPad thread too). I like the idea of the Note 10.1 2014 as an alternative to the iPad, but from what I understand you can't use it (in the US at least) on anything but WiFi. Is this correct? Or can I go to AT&T and start a data plan and get a sim, plug it in and boom, cell connectivity? I don't see any different versions with cell network capabilities. If they're are seperate versions, do they even sell them in the US?
