A couple years ago, I read an article about relying more on the terminal as a way to decrease distractions, thereby increasing efficiency. I finally took this guy's word and spent the past week moving my email and messaging routines to mutt and irssi-xmpp respectively. The programs are running in screen on a server.
In addition to being a command line hipster (ha :P), I can save a small chunk of RAM from not having Gmail as an open tab in Webkit. This is especially helpful for running Lightroom, which enjoys gobbling system memory. Sure, this workflow has limitations (attaching files to emails, for example), but it's a small move that I hope will ultimately wean me off my attachment to electronic communications.
