Challenges with the diversity of the Android Market

For those of you interested in hitting the Android market, Gamasutra has an interesting article about the Android market.  I have to be honest, the idea of publishing to the Android is a bit intimidating, but only because there are so many different form factors to test.  The same goes for Blackberry, but to a lesser degree.  The nice thing about ShiVa is that everything scales to whatever resolution you are running in.  Of course you still need to check that things aren't too small, etc, but at least from what I have seen so far it works pretty well.  I'm hoping that the same can be said for Corona since that will be my next project.
