Subject: Re: [P1] upgrade original clamshell " A 3GB HD is small, and your iBook would really benefit from an upgrade in that department." An external hard drive is also an option. Can go up to 80gb for a reasonable investment, which is what I recently did. But I did not know that I could use OSX on my 300 mzh tangerine. Guess I would install it on my external hard drive, which i have already partitioned? Recently acquired a digital camera so would like to have a way to deal with all the photos along with all the other advantages of OSX.
