Which mobile platform is your favorite?
briansmith: Symbian is a pain in the neck to program for, but you can do anything you want on it, and it has (and will have) a huge marketshare. iPhone and Android are a walk in the park but they both have severe limitations (especially the iPhone). The iPhone is the easiest one to deploy to (thanks to the App Store). I don't have any experience with WinMo. So far, Symbian is my favorite.
