That could only be said by someone who hasn't used FCP.
Oddly enough I have. I use everything and usually do give it a fair shake before I comment on it, which is why I seem to be at odds with quite a number of people on the Internet. Have you used Vegas?
As I said, I'm not a professional. I've found Vegas pretty effective for what I do but as I also said, your choice of hardware will most probably be dictated by the software you choose and that choice will be dictated by not just your preferences but your industry sector.
