Good to Go

I wanted to read PDF books and take notes on longer documents with my iPhone (where the font tends to be too friggin small). This has all the features I was looking for.
Notes, color stars, highlighting, easy and varied sharing options. The auto crop/text flow formatting or whatever they call it works well. It can be wonky with some scanned PDFs books, but this can be overcome. These, combined with the organization functions and general accessibility features that exceed Adobes reader, this app was worth four bucks to me.
I havent used the text-to-speech or multi-language options so you should check out some other reviews of this app if those functions will be a deal breaker for you.
