Besides a bevy of new features, Android's update to 4.4 brought forth a ton of tweaks to the interface through GEL launcher and a fresh round of updated stock apps. There's little doubt Android's user experience and overall design paradigms are continuing to evolve, becoming more refined, usable, and useful.

So far, the red Galaxy S III has been limited strictly to AT&T. If you wanted to get your hands on that device in the color that denotes danger and sexiness (you know, in keeping with the whole calming 'nature' theme), then two-thirds of U.S. mobile users would have to switch carriers. Now, however, you can get a red Galaxy S III 920 from Wal-Mart as long as you don't mind it being a Lumia 920, running Windows Phone, and not being a Galaxy S III at all.
