I recently picked up an 14" iBook G4. I upgraded the RAM so I have a total of 1.12 GB of memory. I am running Tiger. My question is about the longevity of the notebook. Is there a way to tell overall how much life is left in the notebook? The display seems a bit dim I was wondering if I need to replace it? Is there an easy way to upgrade the hard drive? When plugged in I can wiggle the connection just a little. Is it loose on is that normal? Any tips? Thanks in advance. I am enjoying using OSX so far.
