Don't know why, but it seems all reviewers leave out two (I feel) important features of the Nexus 7. The first is that it is one of, if not the only tablet that has a complete 'standalone' GPS built in. This means it does not have to have Wi-Fi or any other connection in order to use the GPS. And there are plenty of apps that need to know where you are!
Secondly, this unit has NFC (Near Field Communication) that allows transferring files, etc., by simply tapping two units together. It also enables purchases via Google Wallet: I have made purchases in stores by just waving the tablet over the NFC cash register terminal. Couldn't be easier. And, BTW, because of it's size, I can carry it with me, in my pants pocket, most everywhere I go.
