I'm pretty impressed by the Holux - often gets a fix indoors or in "urban canyons", and is very small, cheap, and the battery lasts ages.

I'm looking forward to using it more - I live around Boston, MA (non-native), where the directions at intersections are treated as state secrets. The local attitude is "if you don't know where you're going, you shouldn't be here".

I just have to find a good way to mount the N800 in the car. I'm planning to try clipping it to the sun visor.

All that said, like the N800 for me, it's more of a toy than a tool at the moment.
