The guy above said it best. Both Sprint Android phones come with version 1.5. The Android G1 already has 1.6 which is a lot cooler. The Droid will have 2.0. I've seen written around the web - that 1.6 (not 2.0) will be available for the Moment in 2010. I'd wait to get either Sprint Android phone since the difference between 1.5 and 1.6 is pretty big in terms of features.
