I think that you are missing something real here. As OS X Users we are in a unique predicament. We can't shop around and find the best deal available at the time, we have to patiently wait for things to come on Apple's schedule. Sony and Lenovo have their Penryns available with HP and Compaq soon to follow, and all of their Meroms are now on deep discount. I can't investigate those, because they use an operating system that is worthless to me.
I have been waiting since November because all indications had new MBPs at Macworld. Why bother waiting, then? Because Apple doesn't drop their prices as their machines get old - and because while I am willing to pay the quality premium for Apple products, I am not willing to be ripped off. All indications say changes are coming soon, and have for a while.
I was a system builder on the PC side before I switched in 2002 and I am still not entirely accustomed to vendor lock-in. OS X is an incredible operating system, but while I like apple hardware, it's not why I switched. Times like this, where there is an obvious decline in value of a product and apple refuses to tip its hat to that, I wonder how loyal I would be if Linux caught up just a little more. I would pay $500 for an OSX license for any hardware. Having to wait around when I am ready to buy just to keep from being fleeced is maddening.
