BTW, the $1699 G4 tested faster than your $2800 PC, so I guess Mac wins the dollar for dollar arguement, too.
As far as the megahertz myth, Intel proved to me that the numbers are virtually meaningless. In that PC repair and networking class I took, they had four identical computers, except one had a PII chip, one had a Pro chip, and one had an MMX chip, and I don't remember the 4th one. They were all 400MHz chips, and were all made by Intel, yet each computer performed tasks at very different speeds.
Intel proved it, Apple and AMD just helped others realize it.
Take care,
