It is just a greed factor for AT&T.
Yes it is and they have learned from the finest ... Mr Steve Jobs.
When I pay over $3,000 for a loaded 15" MBP, and concurrently purchase a ThinkPad with equal specs for just $1700, Apple Tax rears it's ugly head.
Yes, I use BOTH a PC and Mac, working in a cross platform engineering position that I have held for 14 years. That's a lot of PowerBooks/MacBook Pros and ThinkPads.
In addition speaking from personal experience, these two have identical components in every area, and the argument that Macs last longer is the biggest myth I've ever heard.
As Mac Laptop User and Apple Loyalist, the pricing is no surprise, as I have been paying this kind of difference year after year for my annual upgrade to each manufacturers latest model.
Nor is this post sour grapes, because I really like my Macs and can very easily afford them. It's been, and will continue to be my laptop of choice until it's ruined by Apples migration to the "Post PC" era.
I do indeed give Apple a lot of credit.
They have built an empire off our wallets. Brilliant indeed. Apples prices are legendary. Kudos to the master of smoke and mirrors.
It will be very interesting and revealing to see where Apple stands a few years from now, when Apple is no longer run and or influenced by Steve Jobs.
