just use the gsm for couple seconds, then n900 outperforms every single sirf III equipped unit when cold started 10 to nil.....
Of course my bluetooth GPS receiver lasts 20+ hours on a single charge (yes while on, not standby). That saves significant battery life on my N900 using bluetooth instead of the onboard GPS.

Under normal conditions, the bluetooth GPS will achieve an initial fix in usually less than 1 minute, despite not having been used for several weeks. It also has a significantly stronger fix and "floats" far less than my N900 GPS. Using GPX view on a golf course, my bluetooth GPS normally shows 5-10 ft error. The N900 GPS (while standing still, earpiece up, etc) varies from 15-70 ft error. This is under essentially identical conditions (middle of open fairway).

While the N900 may be faster to get a lock using network, waiting less than a minute for a better more stable lock, doesn't perceptibly change my life. I'll wait.
