Bimmernut, the emotions on the F series runs either hot or cold. Luck with the units seems kind of odd too. Granted most of the folks here are either modding them or looking to solve an issue, and you rarely hear ppl just randomly saying that XXXXX works just like its supposed to.
I've had my F700 for about 6 months and mine has only rebooted itself once, and that was caused by me with a bad file in a mod. Other than that mine has been perfect. Yes, a little slow at times, but nothing in the way of malfunctioning.
I can say that in the mornings heading to work, I have the radio audio playing by the time I get out of the driveway. If you leave it on Ipod or usb drive it takes longer. My bluetooth works great and I have no problems with it even at work.
I work at a Naval Air Station, even with all the RFI, radars etc bluetooth doesn't flinch.
Look around at places like 6ave.com, lots of folks here used them with good results.
