I tried searching this through google and all i could find is average BATTERY life of notebooks. If there is already a thread on this, my bad. I was wondering what the average hardware life of a notebook is. Of course, each case is going to be different and how bad you abuse it and how often you use it will also factor in but in general... I have the last model 15in Powerbook G4. I've upgraded it to 2GB of RAM couple months ago and applecared for a new battery. It seems perfectly fine with an exception of the screen flashing a white ish color everyone it can't process something (going to the top right corner for my all windows magic corner when they're no open applications or pressing delete/clicking else where when it prompts me to answer a question like "Do you really want to delete this song from your itunes library). How long can i hope for this to last me? What is most likely the first thing to go and with regular use and minimal abuse, is there a "best way" to extend the life of my computer? Finally, should I try to sell it on ebay for about 500-600 and use it to purchase a lowend macbook or just live this computer out?
