"i know apple is the best for creating or editing photos/video/music."
I know this will start off the eternal debate between Mac and PC, but what the hell. But the above statement isnt true.
The fact of the matter is... When it comes to video editing, Mac is not better then PC, nor is PC better then Mac. The software is what really counts. And most high-end software suites and packages are available in both Mac and PC verisons.
On the hardware end for video editing, you should have a gig of ram, a pretty hefty hard drive (DV video comes in at about 4 megs per second), a good video card, and a medium to high end processor. After that its just software.
But of course, its not that black and white, as with anything. Both Mac and PC have their strengths and weaknesses.
If you want to get some good suggestions I'd suggest being more specfic about your desired use, skill level, what you hope to eventually move up to (if at all).
