Sorry about the repost, forgot to preview and put up that unreadable wall of text...

Apple's IPhone, Obj-C and you need an intel mac dev platform + Apple dev license. But if you got those yea it's pretty fun to dev on. Not really the same as the others though.

RIM's Blackberry, supports generic j2me and has it's own incompatible java api too.

Nokia's line (Symbian), supports generic j2me.

Android phone we can get in Canada. java based but not the same as generic j2me.

J2ME generic app. Preferred if you just want to make the app once and have it support the largest number of devices. (doesn't allow the really cool stuff though)

Web-based UI. Never tried this since I only work on mobile games.

The other dev handles WinMo though it seems pretty easy to work with.

Also keep in mind that Verizon likes it's apps in BREW. (the biggest money maker in the US by far, though At&t is pretty big too)

And if you're going international, most support various versions of java. (often incompatible though)
