Aside from getting it into USB host mode (which probably had to do with all the flags I'd enabled like R&D mode) it went fine. Any of the problems I had other than that I blame on Windows XP because a reboot fixed them. The new firmware is far more responsive, noticeably faster, and reduces the instances of apps disappearing.

Nokia's got some damned good coders in their midst. What they also probably had was a management team rushing to get the product to market before the software was ready. In the 6 months I've had the 770, I've gone through two updates and the software shows it's growing more mature each time.
