There are more and more indications that we still want paper and handwritten things. You can't beat it for portability. And there are few version compatibility problems with paper -- it pretty much works with all human readers.
At least two methods are now available to synch your actual paper to your digital life.
Livescribe SmartPen is one approach -- a digital pen can link to your computer and upload your notebooks into various forms. (My earlier post on SmartPen here, and a piece I wrote about using a Livescribe as a research tool is here.)
You need the pen, which is actually a small computer. And you need special paper. But you can then hook into a number of other sending and sharing methods.
Moleskine's new smart notebook is another. Image and more about this application here, on PSFK. For this one, you need an app designed to upload pictures you take with your phone into Evernote.
I have high hopes for continued developments in this area that will eventually make the paper to digital translation go easily in either direction.
