My next system is likely going to be an 8 core 2.66 system with 12GB of RAM. Still at least a couple of months off from purchasing (unless Apple decides to do a speed bump first - not holding my breath). Just doing the math (no taxes included for simplicity) it looks like: Full retail = 4999 Edu disc = 4529 (470 savings) Dev disc = 3999 + 499 dev fee (501 savings) Refurb w/ OWC memory = 4314 (685 savings) So as of now it appears that if I don't mind doing refurb then that is the cheapest route. For a brand new machine, the developer discount (if I have the right numbers) is the cheapest even factoring in the cost of the membership fee. Do I have the developer price correct for an ADC Select member? If so, the ADC route seems to make the most sense since for only 185 more than the refurb I get a new machine + access to ADC tools. Am I missing anything? Is the ADC just a one year deal for the $499?
