Darn, I forgot to list it. I won't add it now though, as it would not be fair. There is an Other option for what is worth. If Other gets a huge number of votes, we'll know that options such as J2ME and others have a somewhat large market share among HNers, and it's not all about Android and iOS.

Wrote far to many games for J2ME the best of which was definitely Discworld, some really "great" memories of dealing with the fragmentation that was present. Mobile dev 7 years ago felt like a war against the brick walls that were in the way, no it feels like the handcuffs are off and the only limitation is ourselves and time

+1 for J2ME. Some of us will not let our Nokia 6303's go :)
