Just gotta chuck this out there whenever I hear the legacy Windows argument. You know you can run windows on a Mac either using Bootcamp or Parallels? 
I use Parallels myself.
I'm going to end up the lone Mac fanboy on these forums I can tell 
No sir. I've been a Mac aficionado since 1984. And, have been using a GUI windowing environment and mouse since 1979 or 80 with the Xerox Alto, and then the Xerox Star. (Both highly popular with the Pentagon and large corporations at the time.)
I've also used Microsoft crap since the home brew days on the Altair, then the PC world when I wanted to work on hardware. That is what it is best or; working on it instead of it working with you. You can make the PC work for you, but you better know the correct dance steps.
I had both a PC and and Mac at work. The PC had to be rebooted daily if not hourly, and you better save your work in progress every ten minutes and back up to an alternate drive every hour. I did all my work reports on the MAC because of this, (And just ran an HD back up at the end of the day). When you are facing a report deadline, the last thing you need is to have to fix some registry corruption or why it suddenly won't link to the printer like it did yesterday.
The Mac, I just left running and never even rebooted it for a year... Then we had a power failure during the night. It rebooted by itself and was ready for duty when I came into work that morning, I just had to reopen the applications. It simply did what was asked of it every day.
The PC was just a time sync for cajoling it into doing something useful.
Our company had about a 50% mix of PC and MAC for the general populace at one time. The IT staff required 10 people to keep the PCs running, and 1 or 2 to deal with MAC issues. Because, the engineering tools were in UNIX, we also had Sun workstations on our desks, about 5 people to support those. And, there were FAR less of those than either the PC or MAC community.
In the lab, we had 50-100 PCs for use as test mules for the hardware we developed for it. Repairing them and reinstalling software was simply an accepted time sync, adding to the development costs of the project.
PCs are cheap to buy, expensive to maintain, particularly if your time is at all valuable. MACs are more expensive to buy and cheap to maintain.
I now have an IMAC and MAC mini as well as older MACs from 1995-ish which I was still using up until last year. The PCs I have, have been sitting in the shed for about ten years., long since devoid of any usefulness.
I do use boot camp to run Windows XP when I want to play certain games or use the RC simulator that is only offered for the PC platform. But, mostly I'm using the Mac environment, just for ease of use, and I can rely on it when needed.
It wasn't until Windows 95 that the user interface became useful and almost equivalent to the 1984 MAC environment. And, both were re-engineered (or copied) from the Xerox windowing GUI developed by Xerox in the late 70s and early 80's. Essentially, the early days of the PC set the user community back about ten years in customer ease of use.
Another nice thing about Mac over PC is that virus software isn't absolutely essential for the MAC (add that to the initial cost of a PC). There just are more people trying to get into your Windows than there are for MACs. However, Microsoft sure left plenty of holes in their system for hackers to exploit.
I'm sure an IT guy seeking employment would prefer PCs over a MAC, as there is far more opportunity for being paid to support PCs over the more reliable MACs.
Cheers,
