Hi, as most of you may know, lots of papers come as PDFs these days. Now we have Preview on our Macs, and it does a great job for text-immanent annotation, however you can't export your annotations to further elaborate on your markings and notes. One way to solve this is to open the PDF using Skim, then convert the annotations to its native format and finally export them as (rich) text. It works fine, yet it's not a particularly great experience. A candidate for such an application is Evernote, however it doesn't do PDF annotation, nor can it import the ones you've made in Preview, except for just displaying the PDF with your annotations in it. There are Goodreader, iAnnotate and PDF Expert on the iPad, though only PDF Expert has a Mac version and does mostly the same stuff Skim does, and that one feels like straight out of 10.4 already. Does anyone have a suggestion for a great App to annotate PDFs which I might've overlooked?
