Very interesting article. I've got a 12" ibook G4 that I wouldn't try running it on... but I've been debating a new G5 iMac to replace the old family PC, but have been concerned that a couple of specialty software items wouldn't work with VPC (my son's homeschool curriculum and something else my wife uses)... This of course only fuels my desire for the new iMac... even though it doesn't help me figure out how to pay for it
