The day before Google's(s goog) annual developer conference, Google Glass is getting a lot of improvements. First, although Glass receives subtle hardware tweaks from time to time, its Google Plus page has announced a bump from 1GB to 2GB of RAM and a slightly bigger battery, among "several [other] hardware updates." Second, there are twelve new Glassware apps available for download, including Shazam, Duolingo, and other big names. A complete list is here. Google's I/O conference may be the largest collection of Glass Explorers ever assembled, but we're not expecting a ton of Glass announcements. However, there are three Glass-centered sessions scheduled for Thursday.
