I work from home one day a week. During the 2010 fall semester, this was also the day I taught class and had office hours, which really changed my work-from-home dynamic. Now I am back to normal which includes starting my work day in my slippers around 7am, lunching mid-day, and then chugging through until early evening. I generally get more done at home (mainly reading and writing) than I ever hope to get through when actually in the office, which I know is the key reason so many companies now allow telecommuting - productivity is higher.
Besides the productivity and the ability to work in my slippers, I mostly enjoy the fact that I get to fix lunch in a real kitchen. Today it was carrots and tortilla chips and homemade guacamole. Add a big glass of bubbly water and part of a Top Chef rerun during the lunch break and I was in heaven.
Wish all days could be like this, but alas, can't move the entire museum collection to my living room. It just wouldn't fit.
