Hmm.... Macs for pro video editing?
Have you ever actually seen anybody doing high end video editing?
Because if you have, you'll see people using SGIs, not Macs or PCs. What do you think people at ILM use? SGIs for high end and dual Xeons for lowend stuff. Macs as well... for email.
In the scientific world where FPU and memory transfer rule the day, I don't even smell any macs. High end calculations are done on Alpha clusters, lower end stuff on Athlon clusters. There is no prideful preference there... and C code can be compiled on any platform... and time after time, Macs are left in the dust.
So there is really no argument there.
As far 23 mac screen, they're all made by Samsung. Thing is, if you buy a Samsung one, you get a better price and a 3 year warrantee. If you get an Apple one, you get raped, it looks gay, and you get only 1 year warrantee.
