I work with both windows and apple computer and believe me or not on OSX it is very simple to save a PDF to evernote. I find myself browsing the internet on the mac and reading pdf so i can save it in evernote with one click. I think it is an omission on the windows patform. Every extra step you have to take to put a document in evernote is irritating and unnecessary (believe me we develop software). Why evernote does not pick this up i don't know. Maybe we are not complaining hard enough!
