There was a time when macs were continually behind the curve in both performance and price. Now, macs can go from market priced to overpriced depending on the timing of your purchase.
The thing to note is that computers (Core 2 Duo onwards) are so powerful now that unless you're doing specialist computing, does it really matter if you unwittingly buy outdated hardware, mac or pc?
Full disclosure, I have a mac, but Apple's design is so slick that I think it can transcend the fact that the hardware is not always top notch.
