A possible Mac campaign ad?

I'm not advanced at all in iMovie, etc. but I've had this idea swimming around in my head for a while now.

I'd like to create an ad with different clips of Mac OS X in action and the general hardware line, with the main slogan as 'This is Mac.'

A really basic description, but I'm just wondering whether anyone reckons it's a good idea, and if anyone has any tips.

PS - For music, I was thinking something like Spitfire by Prodigy.

If you know the song / band.
