Being able to control the HVAC of your home is also a plus. Take my office as an example: In the midwestern US, we are in the middle of a heatwave, and the A/C has malfunctioned in our part of the building. With temps pushing 85 it's impossible to be productive. If I were at home, I would be comfortable. Even if my A/C were out at home, I could always take my work to the coffee shop.
