I agree a newer commodity laptop is better for a daily driver under most circumstances. Still if you don't want to watch youtube videos on it a last generation G4 would be that bad IF you have a bunch of usable PPC era software laying about.

The people around here vary in how technical they are. I figured if you can recap a 68k and troubleshoot it then getting a laptop back in operation will not be that hard. But from a never touch the hardware type of user I would stay away from PPC anything as your main machine.
