I compared N810 against a 4-year old Garmin iQue 3600 PDA+GPS combo, and the Garmin is consistently quicker in obtaining a fix. It can take me several minutes to obtain a fix under clear skies with N810, even when GPS has only been off for a few hours. The Garmin averages 35-40 seconds, as normal GPSs should.

The problem is that N810 apparently uses a cheap, low-end, underpowered GPS chip. This thread has more information
