I've found myself over the past year doing pretty much everything online. It's so much easier. No matter where I am, I have access to everything I need. Between gmail, google documents, and google calendar I've found I rarely ever use MS Office at all.

I was holding out for a tablet computer with a "real" OS, as I wanted to be sure I had access to files and documents, but I realize now, I don't have much of that stuff anymore.
