Last September, our office moved from Redwood Shores to San Mateo. The new office is physically much nicer than the old one, and we all have a lot more room and are more comfortable. However, I'm not the only one who is working from home more often. That extra five miles further away (and at least ten minutes' extra drive time) is making several of us work from home more often if our jobs can be done that way.
Besides, it saves me about $8 worth of fuel and a $3 bridge toll.
