Scholar Portfolio: My Assistant Brain

I love computers and hand held devices for expanding access to information. However, at the present I like a more traditional, tangible scholar record keeping system.  Having everything in the palm of my hand sounds wonderful, portable, quick, and light. However, after having lost important files, moved from one computer to the next, had hard drives fail, had connectivity issues, dying batteries, and a thumb drive die with my thesis on it, I have decided that binders are my friend. Who wants to collect years of notes, ideas, essays and other valuable information only to have it lost forever, or not be able to access it when I want it due to connectivity power power issues?
