Nexus 7

When developers attend Google I/O 2013 this week they will probably have a lot to look forward to--in-depth technical sessions, visionary keynotes and major product and service announcements. As they get bombarded with information it could be difficult to remember everything they learn, just as it's easy to forget about what was announced at Google I/O last year. Which is why, before things get underway, it's worth taking a quick look back at I/O 2012 and thinking about the big promise Google made, and which it failed to deliver. I am referring, of course, to the Nexus Q.

Google's second-generation Nexus 7 tablet will reportedly arrive around July and will pack a Qualcomm Snapdragon processor, apparently chosen in part for its ability to tightly integrate with the chipmaker's 3G/LTE baseband modem.

AT&T began offering U-verse Internet customers the choice of a free Xbox 360, Kindle Fire, Nexus 7 Tablet or Sonos Play 3 media player if they add its U-verse TV or voice service to their subscriptions.

Google is pushing its Android 4.2.2 Jelly Bean software update to Nexus-branded devices including Samsung Electronics' Galaxy Nexus and Nexus 10.
