I think it should be mentioned that you most definitely don't need to use Eclipse to develop for Android. If you don't like Eclipse, both of the other major Java IDE's (NetBeans and Intellij) have Android plugins. And, since all the important tools can be run from the command line, really any text editor will do. I wrote my first Android app entirely in Emacs. If you're an OSX user, TextMate would probably be a great choice for Android development.

Also, as I believe the article points out, with Android (or MP7) you can run your development environment in a VM of our choice on top of whatever you normally use as your desktop OS (I do my Android development in an Ubuntu VM on my Windows XP laptop). That's not practical for iPhone development. Putting together a "FrankenMac" is very cumbersome, the resulting VM tends to be unstable and fragile, not to mention that it's against the license agreement for OSX.
