I don't even agree with the multimedia savvy anymore.
The shop I used to work at did a comparison test between a G5 and a P4 3.2ghz (or similar, I forget which exact model), both set up to relatively equal specs. We did computer music studio production (we built U2's live touring rig this year), and the P4 based model blew the G5 away, in every single category. The same has been true lately for video editing and Photoshopping. A PC based system, either AMD or Intel, completely trashes a Mac.
People who base their Mac purchase on the media performance are basing their decision on a factor that was outdated when the G3 came out. Remember, the benchmarks that Mac uses to prove their superiority in Photoshop include one filter, run on Feburary every third February 29th, with the humidity at 62.5% and run while wearing a particular pair of underpants.
Maybe the new Intel chips will make a difference, but it's still very hard to tell at this point. Jobs still isn't gonna allow a total takeover by Windows, so expect alot of problems. Personally, I see Mac getting totally trashed as a studio machine........the same as it is today.
