The fact is, I can go to dell.com and get a laptop for $500. This laptop will do everything I need it to do. That is a good investment.
If I go to apple.com, the cheapest I can get a laptop for is $1000. That's twice the price. Opening word documents won't happen any faster and I don't care if I have 50% or 20% of my battery left at the end of the day.
Apple may APPEAR to be competitively priced, but the thing is if you need a word processing machine, the MacBook is $500 too expensive. If you need a gaming machine, you can get a Dell with an ATI 4570 for $800. The cheepest mac with a dedicated graphics card is $2000.
It's still expensive, get over it.
Also, discussing the price of the desktops. I can build a computer that does what I need it to do, using hi quality but inexpensive parts for less than Apple charges. a lot less. It may not have a server-class processor, but who cares? I certainly don't, not when I can get a quad-core desktop system for under $600 ($800 if you include Windows, I got my legal copy free from Uni)
You do realize that Apple uses the same sound card, firewire card, graphics card, and (in some cases) screens as Dell or HP, right?
