I'm a barrage of questions today! It's non work related this time.
I've finally got round to picking up OS X.3 for my girlfriends iBook. Is it worth formatting the HD and doing a fresh install or can I just upgrade the current OS with out worrying about what it'll do to the system. I've always gone for a clean install on my Windows boxes - should I do the same with the Mac?
If so how do I go about it?! What’s the best way to back up everything? Think there is space left on her iPod to transfer stuff to - however I've no idea how you do that. Really don't want to back up all the MP3's - If I sync the iPod to a clean install will it transfer all the songs back in to iTunes?
The iBooks currently running OS X.2 which was installed over OS X.1.
Any help appreciated

Cheers.
