I bought my ibook 700 Mhz in february.
I noticed two things when switching OS:
1. changes the date and time. It's annoying for me that everytime I switch for example to OS 9 I have to fix the day/time and viceversa.
and
2. Recently makes a strange noise when restart after switching boot OS. It's a sound like a small engine spinning but not loudly.
If anyone has some experience on those things I'll apprecite feedback very much.
Sincerely
Zag.
