@variablepulserate Between March 2003 & September 2009 I had a series of G3 & G4 iBooks, all purchased second-hand. Most were 12-inch, including a FireWire Clamshell and also a 14-inch 1.33 GHz model. Both of those are still used by the retired couple to whom I traded them. One for cash, one for favours rendered. I guess I never had them long enough for such corner cracks to appear.
