Evernote

One of the handiest things I have on my iPad is something called Evernote.  It took me a long time to figure out how to use it.  Basically the service (the premium one for $45 a year is a great deal and allows all sorts of additions including saving file types like Microsoft documents in their original format) allows you to keep all sorts of documents in the cloud and then access them and work with them and send them from almost any type of device.   Thus, I now back up all my reading on to evernote.  When I see something I clip it.  You can define the documents in a number of ways to make them easier to find.   I hope sometime soon it will help me get rid of a lot of desktop clutter.
