Now that my Powerbook is back from repair, I'm very happy with it again, as I type this in a dark room on a backlit keyboard 😎 . Its funny that because I'm so used to have Mac computers working all the time, that I'm shocked and disappointed when other things don't always work all the time. Even though my Powerbook did actually have a bad logic board that needed replacing, first time I've ever had a problem that needed fixing.
