Yesterday there was a very small (under 1MB) update rolling out to the Nexus 7. We were a little perplexed to exactly what it was (I’m always worried Google will finally dumb down the search). Today, Google is finally shedding some light on the OTA, revealing that it was little more than the addition of Google Wallet for the tablet. I think this officially makes mobile transactions on the 7-inch tablet much more inconvenient than, you know, whipping out your actual credit card. Still, for those that finally got their hands on the tablet and never let it leave their side’s, purchasing Slurpees on the Nexus 7 is now officially possible.
