I hate paper and I love Evernote. I use it to store everything. I automatically forward files from my email to my Evernote (including snail mail which is automatically scanned and emailed to me). I take photos of every document I sign and business card I’m given using their iPhone App and I even forward my Workflowy history to Evernote.
Some people may suggest using Dropbox or Google Drive, but Evernote has a specific benefit that makes it kick ass: Search.
Evernote is built around search. All documents, images and photos are scanned and made searchable. This means you can dump everything into one folder and Evernote will make it instantly searchable from any of your devices. No organizing, no tagging, just sweet, sweet search :).
