Is the mobile industry large? massive. However it feels like a broken record when you read press releases such as: Nokia, Vodafone Collaborate on Mobile Java.
I am not trying to say it isn’t important, but there are many other fish in the sea too. How about innovating in those areas? How about seeming like you care about the other communities (e.g. enterprise java in general, not just when accessing it via a phone :)
So much could be done.
