I have a very old iMac G3 that's still working. I was wondering whether I should upgrade it to Tiger or Panther, but I'm not sure whether it would be capable of running OS X. I tried looking for the computer specs, but I couldn't find it. It's running OS 8.6 right now. I am still not sure whether to upgrade, because this computer gives me so many memories. The Operating system and the files give me all these memories from the past, but a simple back-up of all of the files doesn't sound good to me, because the operating system is a big thing. The big question is... should I upgrade? Can I dual boot the system to OS X and 8.6 as well? Please help me. Thanks! EDIT: I also have a MacBook, so I wasn't sure whether I should upgrade it to OS X. I haven't used the iMac for a while, because 8.6 doesn't seem as great as OS X. Do you think I should upgrade it to OS X?
