You are aware that the Mac can run 100% of Windows software, aren't you? And 100% of LINUX... and 100% of UNIX... and DOS, and a bunch of other OSes? All at the same time. Essentially, OS X Macs can run far more software than can Windows.
. . . plus you have to go to Apple for hardware,
Aside from the computer, Macs that is not true. Macs are truly plug and play... I have not run into a peripheral for the PC that does not work on the Mac, usually without installing drivers.
Then too, in all movies that show Mac computers and the people are trying to do something really fast it show the Mac plodding along ...re:Office Space for one ....
Office Space was released in 1999... TWO YEARS before OS X was released. The Macs shown on there were using the previous Mac OS that has absolutely no relationship with OS X on modern Macs. Pundits have reported that the the fastest Windows Vista machine is a Mac.
I think your opinion is based on data that is woefully out of date.
