Hello all. I am considering downsizing my computing to just a laptop and would like some help. This is my system: Model: iMac early 2009 20" 2.66GHz Intel C2D Memory: 8GB(max) Storage: 3TB Seagate Barracuda HDD Issues: Superdrive no longer reads DVDs. It still reads CDs, however. I still also have the following: Original box, packaging, and accessories(wired keyboard/wired mighty mouse). I will also include the original installation media(OS X Leopard) and the Snow Leopard installation disc as well. Everything is in great aesthetic and mechanical working condition(except for the superdrive). Is it reasonable to offer my iMac as an equitable trade for a unibody 15" MBP? Thank you very much in advance.
