Hmmm ... usually 4 satellites are needed for 3D fix and 3 are good enough for a 2D fix given a simple model of the Earth. I know my iBlue external GPS would give me a 2D fix until it finally resolved a full 3D fix. Perhaps that is the step that is missing with the N810s hardware that is giving the perception that it is taking a much slower time to finally complete the fix. Considering there doesn't seem to be anywhere in the included maps software that gives altitude, perhaps the hardware can be kicked into a different "2D" mode that would be sufficient for most ground navigating people.

Sorry ... I was just relaying info what I saw in Jussi's blog in response to someone's complaint about the built in GPS. Didn't mean to not give credit where credit is due ... kudos to your insight.
