People still buy old Macs on ebay;anyone tossing a 9600 or iMac is tossing money.Maybe only $20 to $50 and up depending on model.Why not give it to someone?
There is a Mac site offering old ,color, powerbooks for $49.95 !!! It doesn't take much of a computer to email or download/upload or surf. There are still a lot of people who haven't any computer and such a minimalist solution would be good for them.
Some people forget that not everyone lives in a new house,drives a new car, and has the latest computer,big HDTV, motorhome,etc.
