Anyway.... I've been filled with gadget-lust for the 770 for almost a year now, and I've finally bought one. Actually, I've finally found a good enough excuse to buy one. 1) Will using it for 2-3 months without ever syncing it to a regular computer cause problems? 2) How rugged is it, actually? I'm most concerned about dust and grime getting into the cracks. When it's not in use, it'll hide in my bag, but a fair amount of crap will still get in there. I think that sums it up.... ~Tabor
