Still need a push to drop $1,500 on Google’s Glass headset when they go on sale to all US residents tomorrow? After skipping a couple of months, the team behind it is pushing a big software update later this week that lets it run the freshest version of Android and adds a bunch of new features. Other than switching to Android Kit Kat, Glass is now organizing photos in bundles for easier scrolling, allows for photo replies in Google Hangouts, makes it easier to send feedback and even sorts voice commands to put your most-used ones at the top.
