God, I kind of hope not. I just bought a Mac Pro in December after upgrading from my Power Mac G5 and I'd be bummed if it was already "obsolete".
Hey, I had a thought the other day I'd like to run by some of the old-school Mac users/lovers. One of the only reasons I hesitated when switching to Mac's four years ago was the fact that I built most of my PC units and felt more confident that the parts would be upgradeable. That is, I could usually drop in a new chipset when they came out, assuming the chipset fit the socket and other requirements of the Motherboard.
I realize that custom built PC/Dos based systems are nothing compared to Apple systems (and by nothing I mean mostly different hardware components). However, that may chance with the recent switch to Intel processors (it seems logical to just drop in a new Intel Quad Core Processor Chipset into my Dual Core system for an easy upgrade to Octo machines).
Yet, wouldn't it make sense for Apple to offer customers some sort of upgrade options? Example:
Let's assume I bought a new Mac Pro 2.66, then a few weeks later new Mac Pro's are released. How about:
1) letting that customer trade up for a set amount if new machines become available within 30 or so days of purchase
2) Allowing customers for in-store upgrades of certain components instead of ditching a system (such as chipsets, etc.). When the Quad Core Intel Chipsets came out, why not allow Mac Pro owners to upgrade to Octo systems in-store without doing it themselves and voiding out the Mac warranties???
Wouldn't that appease some PC/Windows owners and coax some of them over to "the Apple side"? lol
