Follow this link and you'll find some tests which show how "slow" the Mac really is these days. My take? Who cares. Create a professional looking DVD on a PC using freeware (or provided) tools and your own video. How long - and how frustrating - will that take you on a PC? How long - and enjoyable - will it be on a Mac? Sure, there are some special cases where raw speed matters, but the Apple advantage has always been measured in more than integer and floating point operations per second. (P.S. Similar ideas here.)
