I have a 2003 iBook G4. After ten minutes of use it locks up and I have to restart. I took it down to the Apple Store and they said after hooking up an external HDD to it that the HDD would need replacing. The cost is supposed to be at least $350 and if there is anything else that's non-mechanical the price will go up even more for repairs. There were three things I was wondering: 1. Is it easy to replace the HDD on an iBook and how cheap is it to do that route. 2. If its even worth fixing and to just junk it and get a new one (which I was planning on doing anyway in a few weeks). 3. To get it fixed and just have it as a backup no matter the cost. I'm looking foward to everyone's input and for taking your time to read this.
