After working on a friend's dual 1.25Ghz G4 tower and being amazed at how quick it is with Leopard, I am now wanting to get a used Mac, as they are a lot cheaper generally than new. For instance, lots of G5 Power Macs can be had for less than a grand. Is this a bad idea, given the rumours of 10.6 being only Intel? Or will Leopard be a viable OS for quite awhile? Or will Apple not ditch their PPC customers? Just curious what you guys/girls think. It'd be a shame for Apple to stop supporting PPC OS-wise, especially considering machines from 2002 still run very, very well and are still very much relevant machines, unlike their Windows counterparts of the same era.
