Googles plan to sell its Glass headset in an extended public beta test was a rather unusual move. Its not often you see consumer hardware get tested in public, particularly something like Glass that has raised a number of privacy concerns since it became available. Through a combination of a slightly bigger battery and software enhancements, Google says that Glass will now last 15 percent longer between charges, as well. The extra RAM will allow for more Glassware [apps] to run in parallel and for each Glassware to start more quickly, says Steve Lee, a Glass product manager. Youll notice the device generally feels a bit faster and more reliable.
