There are two binds of batteries on the Apple website. One for "Opaque iBooks" and one for "Chrystal iBooks". I was wondering which models are which of these. Is my new iBook 800/CD called opaque or chrystal? Also, in pictures of iBooks on the internet the inside looks grayish, silver even. However I have never seen an iBook in real life which looked like that. Were iBook insides ever that colour or is it just how they look in pictures? If the inside ever looked like that, which iBook models have this colour? Thank you for your help.
