A-GPS gets it in seconds, as you download the list via data connection from a nearby stationary GPS reciever.
My understanding of "cold start" is when you attempt to get a "fix" in a location that may be hundreds of miles from where you got your last "fix". For instance, if I drive 50 miles from where I got my last "fix", and then started my bluetooth gps, my N800 will typically show location in less than 60 seconds (cold start). If I turn my gps "off" wait a few minutes and then turn it "on" my N800 will typically show my location in about 20 seconds (warm start). I also understand that there are many circumstances that affects a fix so that at certain times even my $700 Garmin gps can have trouble getting a fix.
