Google Glass got an upgrade on Wednesday, doubling the memory with 2 GB of RAM. Unfortunately for early "Glass Explorers," people who already bought Google Glass don't get the upgrade — it's only for the new version of Glass that will roll out after today's Google I/O developer conference. Since Glass was debuted last year, battery life has improved 20 percent, the company said in a Google Plus post. The updated Google Glass will also feature a new feature that will help users frame photos with the not-at-all-awkward phrase, "OK Glass, show the viewfinder." All Google Glass owners will be able to share way too much information about their lives thanks to the Livestream video-sharing app that hit the MyGlass store on Tuesday.
