Buying a Mac

[ghost_lingering]

Hey, so. I'm buying a new computer, and I'd like to get a Mac that would be decent for vidding. I'm tentatively thinking a 15" powerbook, but I've never owned a Mac before, and I don't know what the hardware essentials are for video editing, so I'd like a bit of guidance. So, uh. What should I get? Or, rather, what system would you get, and what would you consider absolutely nessisary in terms of specifications?

Also, if anyone knows of any good technical guides that are Mac specific, I'd love if you could link them--most of the information that I've found has been for pcs, which has been wonderful...until now.

Thanks much!
