I got an offer to trade my 5 year old PC for an iMac G3 700. Is it worth it? The way i look at it is, its a Mac, its not TOO old, and Its better than a 1.2GHz PC. My uestion is will this run Tiger well? All im looking to do with it is INternet, email, a LITTLE iPhoto, and for my iPod nano. Will it be good for this?
