From a usability point of view, i have used tomtom and garmin, and the tom tom was far superior.
I agree about the TomTom being very usable, though don't take it off road for geocache hunting as the co-ordinate resolution is missing the last digit on mine. Also it assumes you prefer travelling along roads in a car so gets upset when you suddenly turn around and walk back the other way looking for the hidden 'treasure'.
I'm not sure about map and satellite updates from Linux - I do that from my PC at work running Windows. The TomTom One uses a standard SD memory card with an obvious file system so in theory it's just a matter of putting the right files in the right places. I am aware it runs Linux itself, but I haven't tinkered with it, yet.
