In celebration of Nexus 7 shipments, Google has posted the full changelog of Android 4.1 to show us just how sweet their latest iteration of Android is. This way when someone asks you, “what’s different in Android 4.1?”, you’ll have an arsenal of bullet points to toss at them.

Now all we need is for the manufacturers and carriers to get moving on pushing this sweet treat out (yea, I know — we’re still waiting on ICS).

The intrawebs have been buzzing all day with Nexus 7 news.

Samsung is a proud sponsor of the 2012 Olympic games, so you know what that means, don’t you? Commercials! Naturally, you can expect the majority of Samsung’s Olympic commercial spots to feature their new flagship Samsung Galaxy S III device, and why wouldn’t they? It’s an amazing phone, and one that coincidentally was designed for humans <—insert smiley face.
