I feel you on the winter thing. I added an electric heater to my office so I can keep the temperatures a bit higher than the rest of the house (mostly I do this for my fingers, honestly). And through the magic of LEDs I have a fairly ridiculous amount of light I can turn on. Makes winter more bearable when I can make it as bright as high noon in July.

I totally get wanting to go into the office. I would go in a few days a week if they hadn't put our new office 20 miles away. Not close to where anybody lives, but it's in the trendy part of downtown.
