I have IM-clients for both MSN and Google Talk in J2ME. The GMail-client from Google is a J2ME app. I have used tons of games (some bad, some very good), all written in J2ME. I have a really cool J2ME app that interacts with a national map service (eniro.se). I have telnet/SSH client written in J2ME. Yeah, J2ME is ridiculous and completely useless...
