Two years after it was introduced, Google Glass hasn't gotten any cheaper -- although it is a bit more stylish with Diane von Furstenberg frames and international now that it's launched in the UK -- but it is getting better. Not just through one of the many software updates that have reached the headset since its debut either, as its hardware has undergone a mild revision. Google announced that new units are shipping with 2GB of RAM, double the amount previously available, among other tweaks that have improved battery life and made voice search better.

The bad news? The new units aren't coming to existing members of the Explorer Program. Still, everyone with Glass can check out a few new features thanks to a software update, like the viewfinder shown above that helps line up photographs. Also new to Glass are Google Now cards that have been on mobile for a little while, reminding wearers where they parked their car and about any packages that are on the way. The skydive into I/O in 2012 is still one of the more memorable product introductions we've seen, and now we're wondering what else Google has in store for the 2014 conference tomorrow.
