As for customization, i see Android to have the same if not more possibilities than winmo, you can change homescreen layouts and interfaces (spb mobile shell 5 coming soon...) icons, taskbar, wallpapers, bootscreens, dialers, widgets etc.
anything you can think of IMO
As for the EVO, im gonna have to see what the iPhone has in store but personally, id rather see a new Palm webOS device unvieled to get my interest away from the EVO since i much rather webOS to Android even though Palm's status dont look good enough to have a device ready to compete in the same time frame... time will tell
