A friend of mine lent me his EDGE 705 for a couple of months, which got me hooked. Now having to reluctantly give it back, I'm looking to buy a gps unit of my own. The only feature I'm really after is to be able to record my rides and upload them to strava/gc/ridewithgps etc. It is entirely possible that I will have to move house in a couple of months, which would mean getting rid of most of my bikes, so I was thinking of getting Garmin's watch instead of a bike computer, so I could use it without a bike. One thing that worries me is GPS accuracy of a garmin watch compared to a garmin cycle computer when on a bike - are they fairly similar? And as one of my laptops runs linux where garmin software isn't really available, does the watch show up as an external drive so i could upload .gpx files manually from there as I did with the 705?
