Essentially, your premise is flawed, I think this is the source of your ignorance on the subject. Let me fix your premise so that you finally stop this non sensical banter :
Your premise is : If one is looking for a desktop computer and want the best performance at a reasonable price, Apple's current product line does not offer a product for the intended use.
There we go. You can't compare values of things that are non-equivalent. Such a comparison would be highly subjective and in no way indicate any kind of real world value or performance.
So please, stop the useless rants.
I think what he's trying to say is, why would a websurfing/email/family photo oriented customer spend $1,200.00 on the base line iMac desktop when they can get a desktop/monitor package deal from Dell or HP for less then $400.00?
Why would a serious gamer spend $2,000.00 on the ultimate model when they can get a faster, up to date PC for half? Well, we know it's not for the Apple hardware...which is perpetually behind on average by 3 years. The OS? Probably. But does that really matter to the casual user?
