The whole PC vs. Mac debate is IMHO just like the debate of automobile makers.

The Ford vs. Chevy or BMW vs. Mercedes is best for reason X, Y and Z. Really, in computers, automobiles and almost every other product made, there are advantages and disadvantages to each.

I personally started out many years ago earning a living selling, using and supporting Windows PCs and Servers. I still use XP in a VM on my Mac Pro. I use what I need to get the job done. I had to use XP in my laser business because the vendor only supplied the print driver (as of now) for Windows.

I have spent literally countless hours supporting Windows environments over the years. Today I use a Mac as my main system. I use both because in my circumstance it works best for me.

Others, however, may find that they are better suited with Windows, Linux, UNIX, OS/2 or an abacus.

I suggest using what works for you and leaving all the X is better than Y FUD out of the discussion. You likely will not convince anyone unless they try other options with an open mind anyway no matter what the OS or machine.
