Some of that hardware will have physical keyboards. Some of it will not. .... If you build an Android app, you have to decide if you'll optimize it for a physical keyboard on the long edge, or a physical keyboard on the short edge, or a software keyboard. Add touch-screen capabilities to this list, and you have the mess that was software for Windows mobile. Add multi-touch if you want to make it really messy. In the end, 90% of your software's code is going to be dealing with different types of user-input, user-input capabilities and how to interface with the actual code that does stuff. I'm definitely going to agree with you on this being a problem that needs solving before Android being on thousands on devices can be considered a good thing.
