Here are the simple facts at the Company I work for.

We have G5 Macintosh computers
We have AMD and Intel PC with Windows XP pro

At the front end the Mac’s cost a little more
In day-to-day use the Mac’s run better and have a much lower cost to run.

That is the tangible information.

Not the intangible information:

To date we have lost about 3800 hours in our XP machines due to breakdowns and nasty computer viruses. 3800 hours is a like having one person working 40 hours a week for a year and a half.

To date we have lost about 16 hours on our Macintosh computers running OS X. Most of the time lost was due to a few units with hardware issues, that by the way Apple corrected in 24hours or less.

Needless to say we are in the process of removing our PC and will be replacing them with G5 Macs.

So this would be my advise: If you want to play games get a PC running Windows, if you want to get work done and keep you business running get a Macintosh. It is that simple.
