I got 2 PPC Macs in the family (a 1.25 GHz mini and an MDD PowerMac) that are still used daily. Those machines are still quick. If it weren't for forced obsolescence by Apple (and now Mozilla as well it seems), they would be used for a good long while still. How much energy and materials is used to make and fly over a new computer? And what to do with the old one? Onto a trash heep? I'm just a little frustrated. Seems that between cash and environment, cash is the quick choice.
