A flipcam, half a dozen smartphones, bluetooth headsets, and most importantly, a preview of Waze, the crowdsourced traffic app recently launched in the U.S.
I'm getting a Droid on December 6th, and Google Navigation is one of the apps I've most been looking forward to. I commute an hour each way to work every day, with a TomTom GPS (a motorcycle model, great for riding, decent for the car). For some reason the old TomToms' traffic data doesn't work with Verizon. Long story short, I hope to make real-time, crowdsourced traffic data a big part of my travels each day, (and it's just awesome technology), so I'll be following its development closely.
