Nope, the main Avid lines basically use an interface designed back in the early '90's. It's been tweaked here and there, but it's still basically the same.
It's more expensive, partially, because it's a niche product w/a relatively small customer base (video/film pros).
Another reason for the price difference between Avid and FCP is, I believe, Apple has a very low mark up on it's pro software. They basically price the software so low that pro's can't not consider it as a option. The logic being, it might not be quite as good as Avid, but the cost savings greatly out ways the differences in software. Plus, if you want FCP you have to buy Apple hardware (where Apple has higher mark ups and makes it's money). Apple Software, IMO, is a loss leader for its hardware.
