You just don't know what you are talking about.
Even today you simply CANNOT find a tower design in the PC world better than the one in the the Mac Pro, not even close. New Intel Processors are commonly reserved for Mac refreshed hardware. Memory capacity, network capabilities, environmentally friendly and power saving designs... Unibody on the laptops and glass & multi-gesture pads, accelerometer (and now a gyro) on the phones... you PC guys still trapped in the 90's whith your horrid towers and dysfunctional mix of bad hardware and AWFULL software... of course, massification of "crappiness" on the PC world gives you guys some little advantages... but at the rate Mac is expanding, you PC guys will just fulfill your obvious and natural destiny: embrace the greatness of the.
Sure you can. Dell workstations use the same hardware as Mac Pro's do. New intel processors being reserved for Mac Pro doesn't make up for Apple's long update cycles. Yes Apple gets them 1.5 months ahead of other PC vendors, but those other vendors will upgrade their machines in 8 months when intel comes up with slightly faster chips while we wait for 18 months for Mac Pro updates. About network capabilities, all the workstations use the same standards.
And I'm not a PC guy. I have been a mac user for 20 years and never ever used a PC. I own a 8 core Mac Pro 3.2, unibody 17" MBP and other Apple gizmos. But I realize that hardware wise macs are NEVER EVER as fast as their PC cousins. I use macs because I like the OS better than windows. And that's not to say it's more advanced than Windows, just better usability and stability.
So yes, I know what I'm talking about. You just proved to be a troll though.
