Well, the Mac sorely lacks in a lot of areas.

As an example, if you enjoy viruses, repeatedly updating your anti-virus software, reformatting the hard drive, running disk optimization and file defragmenting programs, not being able to take your PC in for free to the Mac Genius bar and having them fix any minor OS or software settings issues or diagnosing problems for you for free, or reloading corrupted software or having to boot from a repair disk to reinstall the main OS once corrupted, you will not like the Mac at all, as you do not get to do any of that cool stuff.

Both Pinnacle and Premier though are reasonably well regarded Windoze environment video editing programs.

A lot of PC pro types use Avid, but I use Final Cut Pro, which is also not perfect, but an update is about ready to come that should be better.
