Most of the computer running PPC are relatively useless for using as main computer because they are getting dated. But they can still be used for a specific purpose like a server or file storage if someone would want to keep one. Don't get me wrong I love my old macs but yet again they are old and 5-6 years ago the newest one came out and 5 years is a long time in the electronics industry.
I actually object to that statement. I, as well as most of us on the PowerPC Forum, Use PowerPC Macs AS our primary machines. Way I see it if you can still use a P4 Socket 478 computer running 512MB or less of RAM and Shitdows XP than they can still support PowerPC. Adobe and Google being the two main companies that chose to abandon PowerPC.
