I am an IT Professional who is certified by Cisco, Microsoft and others. I work in an enterprise level windows environment and I must say this about Mac & PC: If you consider the price and only the usual hardware specs say processor speed, ram or hard drive space then yes a cheaper pc will likely to get the job done for less money. However, you don't buy a mac for only the processor speed, ram or hard drive space. You buy a mac because it has a solid operating system that uses less system resources, boots and launches applications faster then windows XP or Vista.
I am a windows power user using a macbook pro to do my job in a large enterprise, and I'm happy with it.
Thin, solid aluminum construction producing less heat then comparably equipped HP or Dell, 7 Hour battery life, back lit keyboard, excellent display...These are all the things that make our exec's want mac's too.
Aside from mac notebooks, there really is no place for macs in large corporate environments at least for the time being.
Cheers to all the people in the Mac vs PC battle
