Heres a review we did of this camera:
Adventure Online TV review

As far as the mac/pc editing question, if your working with HD the biggest factor is going to be your hardware: processor, RAM, raid setup (and monitors). You can accomplish the majority of the same things whether mac/pc/finalcut/vegas/premiere/etc, but at the end of the day power rules. I had a lot of crashes working with HD with my old PC, upgraded recently to the latest and greatest hardware and its much more stable.
