I'm thinking about selling my 2006 Mac Pro to upgrade to the 2008. The system is in pristine condition, but I never purchased the extended AppleCare and it is now past it's warranty. Does anyone have idea how much this impacts its value, and is there anything I can do to that would help? Also, I noticed on Ebay a lot of sellers will sell their Macs with software included (ie, Adobe Photoshop, iWork, etc), but no discs/serial numbers. Is this legal? Do people just turn a blind eye? The specs: 2*2.66, ATI 1900, 6GB RAM, Leopard, Adobe Photoshop CS3 Extended, iLife 08, iWork 08, Office 2004. Purchase in Jan 07. Any advice/thoughts etc are much appreciated.
