I'm not sure it's important to predict now whether iOS or Android is going to be bigger or more profitable to developers. They're both going to be enormous and they're both going to be around for a long time, just like the Window-Mac horse race from the 1980s to now. There's a lot of money to be made on either - or both. Going back to the Windows-Mac comparison, though, think of all the horses that aren't still in the race from the 1980s: CP/M, Amiga, OS/2, etc. That's the question for the mobile marketplace. What is going to be the mobile equivalent of those? WebOS? Symbian? Windows 7?
