Dude I jumped into Android with both feet and blindfolded not knowing a DAMN thing about Android other than what I had read.
I can say it's one of the best decisions I've ever made! I have an Evo, but Android is Android and it's so awesome, especially compared to WinMo. I upgraded from an HTC Touch which I had for 2 years and that thing was just problem after problem after problem. Crashes, freezes, reboots, etc. etc. What a PITA! I don't think I'll ever go back to a Winblows phone. Android is just fast and sexy out of the box and easy to customize, and on the Evo it flies.
I'm officially an Android convert.
