http://forums.androidcentral.com – I'm this close to going with a Nexus 7, but have a couple questions. With my phone, I use GPS apps to track my location on road trips and around town.

I'm not sure this is a big deal to me, but it would be nice. I'm new to NFC. The specs say NFC (Android Beam). Is that just a Google brand name for NFC? Is there anything I can't do with the Nexus 7 that I could do with other NFC-enabled devices? I primarily want to buy programmabl (HowTos)
