Yeah, I think the gadgets are worth more than the bike

Seriously, the GPS has been really fun for taking detours, running errands, and finding new routes home. It's also displays a scad of trip info on one backlit display including: compass direction, current and max velocity, moving and overall averages, distance, distance to destination, as well as stopped and moving time, which frees up the Polar for things like elevation and Calories. It can also give voice prompts and adjusts backlighting at sunrise and sunset. It's more useful than I thought it would be, but it's a poor man's Garmin 705.
