Hello everyone, I am new here, and I am planing to buy an iPad 2 as soon as I can. That is why I am starting to buy the important apps that I will need once it arrives. One of the most important apps that I will need is one to work with pdf (correct, outline, etc...) I have seen that the two apps that better comments have and that are more talked in the web are GoodReader and PDF Expert. From the first look it looks that GoodReader is much more complete, but however a lot of people that have both say that they need them for different things. What has PDF Expert that GoodReader doesn't? Which one would you recommend me to buy? Thank you very much!
