@DavidCar: Thanks for the info. The issue is, however, that my main reason for purchasing an ADC membership would be for the hardware discount. I see the other components (i.e., development tools) of ADC as a secondary benefit. So, I would like to know before paying for ADC whether or not it is worth it from a discount standpoint. The link you posted seems to want me to log in with an ADC account before viewing hardware prices, which puts me in a bit of a catch-22 (don't want to buy ADC unless it provides worthwhile discounts, but can't see the discounts w/out ADC). Though if it's true that you receive new versions of OS X as part of it, that makes it worth the price! (Although, I assume when you renew yearly, if you are no longer a student you no longer get the $99 price.)
Other users have mentioned ~$500 discount on MBPs. However, this could change once the new MBP is released. So, I could just wait until they are released and ask somebody with an ADC account what the prices are. But I'm from Missouri (the Show-Me State), which means that I like to see things for myself...
I guess this is a bit off-topic, but it is (for me, personally) directly related to the purchase of a new MBP, which I will do as soon as the new ones are released...
Edit: I'm an idiot. You can see the Developer's store without logging in. Sorry! DavidCar: Thanks again for the link! That's great!
