Froyo is great and all, but Google just blew our minds with two previews of upcoming Android features at I/O: OTA application installation and remote music streaming. OTA installation is just as simple as you'd expect -- after browsing to an app on your desktop, you can push it to your phone and install it with just a single click, all done over the air. Interestingly, Google also showed music being purchased and transferred from Android Marketplace in the same way, which could indicate a deeper push towards music integration, or just be a nice demo. Either way, it's pretty slick stuff -- the fewer wires we have to carry, the better.
The remote music streaming is a little crazier: Google bought a company called Simplify Media, which makes a bit of desktop software that can stream all your music directly from iTunes to your phone. The demo was quite slick -- you just open the app and push "all," and all your music is instantly available. Whether or not this'll work over 3G or be limited to the local network is still up in the air, but we're dying to try it out.
