A client bought me an iPhone for Christmas. It's a pretty darn slick gadget, although I doubt that I'll keep a phone plan on it (I'm pretty much either at home in my wifi bubble all day long and, when I go out, I'm often going to beaches and other salty places).
For the moment, though, I have an unlimited data plan. I may try Twittering and see if that becomes interesting. Here's my feed: http://twitter.com/lobrien
