Microsoft makes you wait at least two years for a bug fix. You can move a network printer and print to it without reconfiguring. If you connect your network printer to another computer, you don't have to do anything. In Windows, if you do the same thing, every computer that wants to print to that printer has to be reconfigured. I'm sure that IS managers everywhere love this little gem.
Macintoshes are easier to support.
I was never really certain that this was true, but I've finally heard it from too many reliable sources. I personally know someone who is one of two people who support 158 Macs at their company. By comparison, a previous employer of mine had three people supporting 50 Windows computers. Think about that. At my previous employer, there was one support person for every 17 computers.
