I'm not interested in high-end effects. Just take clips, set start and end points, fix the audio so it's audible (my current beef with Windows Live Movie Maker), do some voice-over and add titles/captions.

And longevity won't be a problem. I've decided camera and computer are a package now. As long as I'm using this camera I'll use whatever computer I end up getting. When it's time to upgrade either, I'll upgrade both.

In the meantime, I'll make sure I burn copies of all the original, uncompressed video in case I ever want to go back and grab clips.
