i spent $500 on this crap it keeps crashing my machine. not to mention Apple charged me $45 in shipping and i didn't even get any stickers! I've done this like 5 times. I'll run the Airport utility and the whole computer (mouse cursor and all) freezez. So then I restart and reset the PPrma, run disk utility and it does it again. I've got a PB g4 17-in 1.5 Ghz. Running Leopard (all software updated) permissions repaired. SCREW YOU STEVE, I WANTA MY STICKERS!!!
