There is a big market in used Cracs ;) which may be worth looking at. I upgraded my 12 year old machine to one merely eight years old, so I could keep clinging to the edge of the support cliff for a few more years.

The abyss is nice and cozy. That claim that it gazes back is just slander. But if you do make the leap from the Crac frying pan into the linux fire, I'd be happy to take your old copy of CS5 off your hands. My copy is even older (CS4).
