I've got a new uj 815 superdrive that I'm wondering if it would be okay to put in a 1ghz iBook 12" with a broken combo drive. Do you all think these 12" ibooks need superdrives? I also have a newish combo drive I can drop into it. The 'book is out of warranty. Also, I don't know and have never burned a dvd on any of my ibooks or powerbooks, so don't know the weaknesses or strengths of the uj815, uj835 or uj845 superdrives. Any thoughts?
