I’ve always been pretty much a middleware and enterprise web guy. I got thrown into some E2E applications that were talking to mobile devices (J2ME) a few years ago and I picked it up pretty quickly.
The reason that I haven’t done any iphone or android work? I’m busy earning a living and my work doesn’t appear to be slowing down anytime soon.
Don’t get me wrong, I’m always learning a few new things here and there (I read alot) but going full bore into doing phone development on a new platform requires an investment in equipment (you need at least one phone to develop to) and quite a bit of time.
And, frankly, I’d rather do the server side piece in a smartphone app than the client UI anyways 😉
