And I don't want the PC vs. Mac argument either.
These forums are hard to express everything since all we have is text and I'm not writing a novel...I think you and I basically agree.
The only difference I see, that you brought up, is the Desktop definition. I do not consider the Mac Pro a desktop. It is a workstation. Dell and others sell "workstations" too. The Mini may be a desktop offering, but it is not a computer "system" which has generally been defined since the early 80's as a computer, mouse, keyboard, and monitor. That's why I didn't count the Mini here...because Mr. Consumer would have to buy a-la-carte and that's kinda getting away from the point of buying a "desktop". Again, hard to put a black and white line on definitions but all of my posts on this topic are for the average Joe, walking into Apple, looking to see how much their first destkop Mac is going to cost.
The cheapest Mini is $599 + $49 for mouse +$49 for keyboard which is basically $699 before a monitor...buy Apple's ONLY MONITOR OFFERING on Apple.com which is $899 for a 24" display and you have a whopping $1596 for a Mini desktop system.
