In case you're not clued into the developer's loop when it comes to all things Android, you might not be aware that there's a brand-spanking-new version of the SDK out right now. The platform charmed developers with its very open conception, but unfortunately the first SDK had a lot of deficiencies, which now have been corrected by Google. The new kit is replete with new apps, a new skin, and tightened-up functionality. In fact, it's almost like a whole new OS. Although no commercially available Android-based phones have been created by now, but many manufacturers presented concepts at Mobile World Congress.
