I was just thinking last night that they seem really, really nifty, and I'd like one. The tipping point came when I started noticing the droid bar codes on some of my favorite blogs. I totally want to be able to just walk around scanning things. :p
To be honest, though, I doubt I'll ever bother getting one, or an iPhone, or any other smartphone. Although I can easily envision particular circumstances where one of the apps might come in handy, those are rare instances. I can easily go 3 days without touching the mobile phone I've got now.
But, if I suddenly got, you know, a life... I'd totally want one of these phones!
