Posted too soon! Meant to add that that is assuming you've got to have software that runs only on an Intel processor. Be warned that some of the software you use now probably won't be compatible, and you'll either have to buy new software(which, I suspect, is the reason we are always being pushed to upgrade) or run two computers. I have a perfectly good scanner/printer that which will not run when connected to my Intel-based Mac, so I print from my PowerPC unit. It's a pain, but I don't want to buy another printer.
