You pay a premium for going for the top of the line. Case in point, the 23" Cinema Display, which lost nearly half its value overnight. Case in point the "old" 1.25 dual Power Macs, which lost a ton of money overnight.
Your investment will depreciate less, both absolutely and percentage wise, if you don't buy the top of the line. And you'll spend more up front. The result is that you can upgrade more frequently and thus get faster and more feature-rich machines on a more consistent basis.
