Ive just published my iPad / iPhone PDF reader roundup thoroughly comparing no less than 36 (!) titles. Please check out it at http://www.iphonelife.com/blog/87/ultimate-pdf-reader-roundup Unfortunately, unlike all of my sorter articles and roundups, I dont have the time to convert (keeping in mind the article size / image number restrictions) and maintain the future updates of the article here (and a lot of other iOS forums); this is why Im not cross-posting the entire article here. Hope just clicking the link wont be a big trouble ;-) Opinions are welcome!
The article serves as a great pdf reader resource. Thanks for the link. I bought Readdle docs during their 3 year anniversary for only a buck. It's nice to see that I made a pretty good choice as I've not the time or resources to sample all readers as you have done for your article.
Thanks! Yup, Readdle is one of the best apps, particularly now that it received annotation capabilities.
