Wow, what a story... isn't a time to ask for money back? Since I got my first Mac (Mac Pro) the only things I had... problems. Never had this expirience with PC. In fact my few 7 - 8 years old PC's seems more reliable then new MacPro. By the way,my MacPro in dealers repair shop, second month now. I'm not taking it back until they fix it or replace the unit.
Regading Kernel panic message - I had too... The funny thinks U can't reboot it like on PC. My mac just didn't respond on it at all... few hours of waiting never help... I don't know.. I don't want Mac anymore! If was able to take my money back I would take them.
