I was in a similar situation about a month ago -- no smartphone, felt like I was falling behind. I ended up getting an iPhone, because it's what people have now, and there's probably a bigger market for contract work on it right now. I also have a Mac, though. Longer-term, I'm betting on Android to overtake the other platforms (mostly as a matter of cost), but it's still in the stage where startups and early-adopter types are the main users, as opposed to the very mainstream iPhone.
