You need to go to Japan more often. I worked quite a lot with NTT DoCoMo and they had amazingly useful games and apps. Everything from a bank machine locator to physical vending machine purchases (with NFC). They had motion sensor support in J2ME devices that they used mostly for fishing/golf games circa 2003-2004 (don't hold me at the dates my memory is the gray equivalent of Swiss cheese). Anyway, J2ME had a lot of levels CDC was pretty much Android equivalent but it didn't have GUI API on top of it because Sun disallowed MIDP on top of CDC and didn't offer anything other than AGUI which nobody used... I can go into endless details here but generally, the reason J2ME failed was that it was a tool built in 1999 with a single moderate update in 2004 and nothing else!
