Totally agree. Iceberg and indeed an iPod touch was my first foray into ebook reading so it was a valuable lesson to learn for me. However, I'm confident that Apple will be around for awhile and do indeed have iBooks from them. Mostly free though. I buy mainly from Amazon but due to recession loads of businesses who I felt would be around forever doesn't give me any confidence any more. I love reading iBooks and is my favourite app but I read all my PDFs in Goodreader now so it's a toss up between the two apps (reading that is). I'm a bookworm and I can't imagine life without books. It's the main reason for switching from iPod touch-iPhone-iPad.
