I currently own a 4,1 Black MacBook (2.4GHz), with 4GB RAM and a Hitachi 7200RPM 750GB HDD. At the moment, I have limited funds to upgrade to a new machine, but I also see the end of the BlackBook with the onset of OS X 10.8 when support will be (virtually) terminated, except for security updates for 10.7. While I would prefer to wait until the next update or even Haswell, the problem for me is that the BlackBook cannot accept enough RAM to properly run OS X 10.7 and my VMs in Fusion 4, so upgrading my machine has ended with 10.6.8. Consequently, I am considering selling my BlackBook before its value drops further, and purchasing a used machine from CraigsList (mid-2010 or early-2011 model, depending on price). Questions: Are any other BlackBook owners considering selling or did you already sell?
