Android is really great for competition. All these handset makers can compete with each other on pricing, features, performance and design and not worry about the OS or developing their own third party application library. I don't think Android will fully Windows-ize the handset market though because both Apple and RIM are very strong. It could go 20/20/20 with the last 20% being a mix-mash of WebOS, Windows Mobile, etc. I think Nokia will jump on the Android train sooner or later. Maybe Palm as well. The way things are heading I'm not sure Windows Mobile is going to even exist in a few years. I think it's more likely Microsoft will make a first party Zune Phone and WM will be forgotten.
