Interesting reading through this thread. Someone around page 30 mentioned he had ordered the $4299 full boat configuration, and was congratulated for being the first. I had said the same thing on page 12. No matter, I doubt I was the first.
My philosophy is this: nobody has ever complained that their computer was too fast, had too much memory, or had too much storage. The opposite is often true.
I keep my computers (and my cars) longer than most folks, so I buy maxed-out configurations up front to get the longest useful life out of them.
This philopshy is how I believe all technology purchases should be. There is no point in buying something if it will have to be replaced in 2 years. You pay upfront a large amount of money and you're almost guaranteed it will last a long time. I have a 2008 unibody MBP, it's 8 years old now. Still runs like a champ, although it is showing it's age.
