OS X vs. Vista comparison in Popular Mechanics.... Here is the link:

In our speed trials, however, Leopard OS trounced Vista in all-important tasks such as boot-up, shutdown and program-launch times. We even tested Vista on the Macs using Apples platform-switching Boot Camp softwareand found that both Apple computers ran Vista faster than our PCs did.

Aside from the Gateway costing $300 more than the Mac and having similiar hardware in the first comparison, but the Gateway has 3x more memory than the Mac, the latter of which has a little higher clock speed, as you can see Leopard trounces on Vista!
What is remarkable for businesses is the efficency gain of the Mac. Leopard boots up 4x faster, shuts down 10x faster, Safari launches 2x faster, even Microsoft Word is faster on Leopard.
Let's just very conservatively look at a few of these items that on average a company's employees do everyday: turn on their computers, turn off their computers, launch their OSes standard browser, work in a word processor. They likely do some of these things many times per day on average, but at least once and I feel like being kind to Vista today...
The sum of these actions above are 40.2 seconds on the Mac, 128.8 seconds on the PC.
Let's say your company has 500 employees that are costing the company on average $20/hour. Every hour they work earns the company some profit too, hopefully, but let's be really conservative and just add up: time per employee * # employees * cost, and and compare...
Here we see a 500 employee company is very conservatively losing $14,767 dollars a day in productivity on Windows, just looking at a few common daily actions. In other words, that is the cost of ten new iMacs per day at retail cost. So a smaller company of 50 could buy one new iMac per day. My current company would save ~$45,000 a day. The biggest company I worked for would lose $148,000 a day by this comparison if they switched from UNIX to Vista, not counting any other costs such as hardware.
