Well, I don't know about everyone else, but my PowerPC machines are going to be put to good use still, especially my recently acquired PowerMac G5. I plan on maxing out the RAM to 8GB, and installing a 500GB HD, so that I can use it as my Photo Editor/File Server while I am building my gaming PC.
My PowerPC isn't dying anytime soon!
