I got my first apple 4S as a gift recently and I instantly fell in love with iBooks. But seeing how all 99.9% of my books are scanned PDFs instead of epubs, the lack of support for PDFs really breaks my heart. I brissed them, OCR'ed (via adobe xi pro trial) and then converted them to epubs (via calibre), but it's a lot of hassle and they don't work. What I need is really simple: - A clean full screen view - Smooth continuous vertical scrolling like iBook - Horizontal screen lock when scrolling (defaulted in iBook) - Ability to make simple annotations like iBook - Ability to find my notes easily (like in iBook, tap notes and you can see all the notes, tap specific note and it brings you to the highlighted text) I don't mind paying a little, but I'd only like to buy ONE app. I don't need the high end functions, I just need apps to perform my aforementioned requirements perfectly.
