? overwrite 10.3.9. with 10.5

Hi

(Apologies if this has already appeared - i went to preview and it dissapeared!)

I recently bought a fab new macbook to replace my trust 4(ish) year old G4i-book. The macbook came with 2, 10.5 disks.

Questions:

Can I use the disks to write over the 10.3.9?

Is there any benefits / point, other than being able to sync my nano which I currently can't do on my ibook since the OS won't let me.

Cheers,

TIA

No. The MacBook discs only work on MacBooks.

You need the retail version.
