I was always an ardent map-user, maps were my thing since I was at school, but earlier this year decided to take up a special offer on a Tom Tom ONE as I had a lot of solo driving to unfamiliar places coming up. I have to say I don't regret getting one, although I still keep a paper map handy just in case, I rarely need to pull over to read it, I just go where John Cleese tells me. I found a better route locally using a "B" road to somewhere I go regularly that I hadn't even considered; the Tom Tom said it was quickest and it certainly beat my original just using "A" roads by several minutes. I also have the traffic receiver which can be useful if it finds a valid delay on your route, and the speed camera add-on which is pretty much a must-have, along with the "nag" sound for when you are going faster than the speed limit. My only gripes are that it only remembers favourite destinations, not routes, it would be quicker if you could ask it do give you the same route it gave you last week rather than recalculating. A lot of the road speed limits are wrong so you get nagged over 30 in a 60 limit for example. And I'd like to see a "most economical" route option in these days of costly petrol. Some of the Tom Toms now have this "smart routes" feature that will give you a different route at different times of day to avoid traffic though, which is a step in the right direction. All in all pretty good.
