Well, one thing I have found is that, as soon as I am done with paid work for the day, I need to get *away* from my desk and go somewhere else. This means that I'm spending a lot of time using my computer in much less ergonomic setups, as I had a nice ergonomic setup at work and a nice one at home, and now I've only got one nice ergonomic setup. It also means that I'm doing all of my photography work on the small laptop monitor rather than my larger one, because I need the larger monitor for my paid work. There are huge benefits to working from home, but some real downsides as well. I sure don't miss 11 hours a week of commuting, that's for sure.
