In case you forgot, or didn’t know in the first place, the Nexus 4 and Nexus 10 arrived today. The new smartphone and tablet joined the Nexus 7 as devices available for purchase in the Google Play store.  If you’ve been waiting to get your hands on the latest smartphone from LG or that new super-high-resolution Samsung tablet then today’s your day.  We’ve seen reports that people are having trouble completing orders or that some of them are not available. Our advice: just keep checking back over the course of the day.  Either it gets ironed out and you get your device or Google tells us it’s sold out.
