Android cannot be the new "windows" because alot of decisions leading up to windows in it's current incarnation were driven by the anti-competitive nature of Microsoft. Android takes the best aspects of windows' business strategies and incorporates them in an open environment.

So I guess if you are saying android is the phone to run on a bunch of random hardware which will outsell apple, yes, android is the new windows of cellphones. In the end it's closer to a user-friendly linux.
