I used to upgrade my machines fairly recently by selling the old ones and putting the sale price of the previous mac towards the new machine. That strategy worked fairly well in the past when PowerPC Macs had amazing resale value, but I can't help but notice that the newer Intel Macs don't seem to share this advantage. Was looking around eBay at some ended listings and noticed that for the older generation 2.0Ghz Core Duo Macbook Pros, bid prices finish barely over 1 grand, pretty sad for a machine that is less than 1 year old and retailed for $1999. Even the newest 2.33Ghz C2D ones went for about 200 less than EDU pricing, and that is for those that came with a 160GB hard drive upgrade Is the lousy build quality of new Macs affecting resale value? Or is it something else?
