Windows is just a poor copy of the MAC OS. If you want to be a real PC man you should stick with DOS.
Macs cost more but they usually come with more. If the clock speed is the same the Mac will be faster to use.
I'm using the same Mac I bought over four years ago and it's still faster than the one year old PC at work that gets a Windows update every few days and needs an intrusive virus program.
My Mac came with a backup program that works in the background, my PC came with one that needs constant supervision.
For less than $100 I can run all my PC programs on my Mac almost as fast as on a PC, not that I want to.
Besides, my Mac was assembled by a very much nicer class of Chinese people than assembled my PC.
