I voted YES - I don't know why but I've got fix in reasonable time. Question is what is "reasonable".
I'm not using it extensively because of lack of good navigation software (I don't like maps in maemo-mapper If I have to - I use wayfinder maps) and increased current consumption.
Sometimes I'm impressed that it locks at 100km/h in few minutes.
Usually I don't have to wait longer than 2-3minutes max to get fix under open sky.
Indoors - it doesn't get lock - as my bluetooth "evermore" crap gps based on Atmel Antaris chip.
For me - they both are same quality.
Once I've compared it to SirfIII - no doubt Sirf locked itself after 30-40sec and was better but no need to cry for me on n810's GPS performance for me.
