*thinks*
You know, I think everyone has very vaild points in this, what is now turning out to be a debate between "real" mac fans, and "realistic" fans! A couple of points :
1) We all know, Windows is ridiculously bad. Have you tried using it? Frankly it doesn't matter whether it's a Dual core Pentium 7 or a Celeron - it's the code, the malware, the incompatible drivers, the mish-mash software etc...that is what makes the platform bad.
2) The megahertz myth apparently has significance here. How many Pentium's are up to 1.25 Ghz FSB?
3) My emac G4 has plenty of power to run Logic Pro 7 and various software synths and samplers at once. True, a little bouncing goes on here and there, but it's a rock. Try doing that on a 1.25 Ghz Celeron Processor using somthing similar. A Joke!
4) Apple is a MUCH smaller organization than Intel or the like. Now, I know that IBM makes the processors before people come and poke me, however look at what Apple are managing to throw out from only somthing like 10,000-20,000 employees. All the software, hardware, display, Airport, music store (Which as I always say IS truly revolutionary. You try and bargain ANYTHING with recoord companies and see what response you get)
The fact is, it shouldn't matter whether our G5's come with 2.5 or even 3.5 GHz processors. Its not the point. The fact is that we are developing - moving on. I chose the mac platform knowing I was paying double and getting half the speed but I did it because it is recognized as the best in the business where I work. From my perspective, 18 months ago I brought my Ti Powerbook running at 867Mhz. Now we're up to around 2.7 (rumored) Ghz. That to me, is an improvement - and when I look to upgrade, I know I have a plausable, economically viable, upgrade route to follow.
