I have an older 733Mhz Quicksilver G4 tower with 80GB 7200RPM HD and 384MB of RAM. The newly out eMacs look to be great deal, as I am not the kind of person that likes to fiddle with the innards of my computer unless necessary. Please help me to discuss the pros and cons of upgrading my current tower vs. buying a new SuperDrive eMac. Since I find my tower to still be more than adequate, should I keep it for another year or two until it is not useful to me and then upgrade? PS. I am an educator, so any Apple store purchases will reflect education discounts.
