Geocaching, anyone?

I recently bought a small bluetooth GPS receiver. 32 channels, 20+ hours battery life, technically (on the documentation, at least) no Mac support. To my surprise, getting it to work well on the Mac was just a matter of pairing it and downloading the latest version of Google Earth. It cost me SGD140 (kind of an Apple staff price from the distributor), but all in all, a decent GPS solution for the Mac. Warning though, tempting as it might be, try not to drive with a MacBook Pro open on the passenger seat and incessantly checking on the route taken
