1st. Sorry for the serial # stuff I placed in another thread. 2nd. I have seen the used computer market for Mac have been growing lately. I think the reason of that is because (at list I do) people think "if my computer won't be the fastest in the market I can get a cheaper one any way". Another reason would be that 90% of the aplications ar running fast enough with current systems (except video related), so, why spending such amount of money in a new computer when I can get a lot of speed for almost half the price?
