I use both Mac OS X and Windows XP Professional. I think the main differences are:
X - built on UNIX so it's very stable. Fewer security issues.
XP - More choice of software, particularly games.
It's now what the marketing types call a 'mature market' so there are fewer real differences. It's more to do with style and image now.

I've used Macs since 1987 so I'm pretty well "dyed in the wool". My sons use XP but, although their Pentium 2.4GHz feels a little faster than my G4 1.4GHz Mac, I find it a little "clunky" to use. It's not as intuitive and the graphics are less refined.
The worst thing about all the Windows PCs that I've used recently is the darn spyware and pop-ups that plague Internet Explorer. With "Firefox" offering a simple cure, I can't understand why people plod on with I.E. and Outlook Express.
I agree that Macs have far less games than Windows (but more are appearing on the market every week) and generally run them more slowly but I have to ask - why would anyone want games on a computer used for business?
And with Windows having such big security loopholes, why would anyone use Windows for business?* The only software I can think of that doesn't have a direct equivalent (often better) for Mac is "Sage" accounting software. Thankfully, I'm not an accountant.
*You can't quote "cost" as being a reason for using Windows for business. The "cost of ownership" of a Mac is the same or lower over 3 years and, as most Macs get replaced every 5 years (compared with 3 years for PCs) the real cost is probably lower. Macs cost more to buy new but are more reliable.
I tend to buy my Macs second hand. They will then last at least 5 years, requiring only a memory battery and hard drive during that time. Total maintenance cost around £50.
The biggest penalty in changing to a Mac is the software cost. Microsoft Office will set you back around £300 and you'll probably have to invest in a new scanner and printer because you'll want Firewire versions. But I'm sure the same comment applies if I were to switch to Windows. Unless I relied on pirate software, I'd have to buy new programmes.
BTW if you do decide to buy a Mac, please plan to use it in tandem with the PC for at least a year. The switch will be much easier if you make the learning curve shallow.
The Mac Mini
looks like a good buy at first, until you count the cost of a new keyboard, mouse, monitor, scanner, printer....
(C'mon, there's no way you want to use that clunky PC keyboard with a beautiful Mac Mini!)
My vote goes to the Apple Mac G4/400 (or faster version) these "old" units can be snapped up used from £300 including keyboard, mouse, monitor and software. And you'll be amazed what you can do with them. Yes, OK, PhotoShop rendering will be noticeably slower compared with the latest P4 Pentium but just try "surfing the net" without worrying about pop-ups, viruses, trojans and spyware.
Jeez, you got me going there. Good job nobody mentioned my other favourite topic - smoking!
