Yeah OS X is great but why is Apple picking on Microsoft 989
No, you made up your own definitions:
"a PC must have Personal data on it... otherwise it's just computer... not a "Personal Computer"."
or
"yes, but a good 40% of that 200 million cannot be considered PCs. they are just dumb terminals in factories, cash registers, glorified typewriters, backend signage, etc."
These are non-standard definitions, at best. Using a PC for word processing - "glorified typewriter" - doesn't count as personal computing? And what in the world is "personal data"? How about citing a source for your definitions?
But Apple can sell systems at a lower price than PC vendors since they are not encumbered by the Microsoft Tax. Going forward, Apple will always have the lower price for said systems...
If you buy 1000 PCs from HP, you can replace or supplement them by buying from Dell or someone else. You can play vendor against vendor to get a better price, or some other benefits. If you buy 1000 PCs from Apple, there is no alternative vendor. Only Apple sells OS X boxes.
OSX Server? That fits your definition of a "personal computer" too?
Why would a company buy a Mac to run Windows? Have you even worked in a business environment? It sure doesn't sound like it.
