I am retired, but I have worked from home for months several times during my career. Besides avoiding an hour long commute each way, I could also take a break and do some minor chores at home, fix my lunch from my own fridge, not be so tired after work, more or less set my own hours not dictated by trying to avoid rush hour traffic, and be able to do things before and after work because I was already home not spending that time driving.

That and as a s/w dev, it was a lot more productive to be able to concentrate in a quiet more comfortable environment.
