OK, I just got my own eeePC 901 to take on travel instead of my 12" powerbook. Love the little guy but can't even do something simple like download cache waypoints.
Machine: eeePC 901 ($449 in case you are interested)
OS: Ubuntu 8.04 (hardy)
GPS: Garmin 60csx
Browser: Firefox 3.0.3
One option would be to install wine, then a windows version of Firefox, then use Garmin Communicator through wine. That seems cumbersome and against the reason I went with Linux. Anyone have luck getting a plug-in to work to do simple things like waypoint downloads with Linux directly?
