I have constantly critisised the GPS in the N810 as being next to worthless, but i installed the AGPS thing today (no idea what you were supposed to do with it), ran it - it had a dot on the UK. Quit it, fired up maemo mapper, downloaded some maps, put the N810 in its sleeve, threw it in my rucksack, threw my rucksack in the car and drove to a city a fair distance away. Then I parked in a multistory, went to get a drink, then went to find a bike shop. I got the N810 to look at the map I didn't even think of using the GPS as it is normally to slow to be worth the effort, and there on maemo mapper was a red line tracking the journey into the city, and then a set of squiggles showing the track of me walking around.

I have never been so impressed with it. It is actually good enough to use now.
