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.

It's only an hour old - it's not as if this is precise science in any event. Phones with J2ME are very, very widespread. Granted, they don't do much, and are not the future, but it's probably still an interesting space for the right kind of niche product.

Yeah, give it time. It usually takes the BlackBerry people a few years to catch up to the present.

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 :)

Not only on old phones, think about all those Chinese ripoffs of the iPhone, Nokia, etc... yeah! running J2ME!

True. Also consider most of the world of Nokia Series 40, which by far destroys any other mobile operating system:

"Analyst estimates place the total number of devices shipped with S40 close to 1.5 billion, as of the end of 2010" [1]
