My team is telecommuting this week due to construction.
Today was day 1 and I can't believe how much I got done

The lack of distractions and nonsense was refreshing. There are times when the team needs to be together and for security reasons the system was slower but still - wow
Anyone do this regularly or even on a part time basis? What are the positives / negatives that you experience?
FYI - My only DS is a 17 so no small children in our home.
My husband telecommutes, I am a SAHM and I homeschool my DS8. So we are all home all the time

DD goes to school. Most of the time it's great, but we can get on each others nerves. He is a software developer.
DH goes to the office once or twice a week (sometimes more, sometimes less). He locks himself in the office and comes out when he wants coffee or food. He spends most of the day in front of the laptops with Yahoo messenger running and on the phone almost all day long. I can never use the phone, and I have to keep DS quiet and away from DH office whenever he is on the phone. DS and I often leave the house when DH has a big important meeting or is working on something that requires intense concentration.
One of the problems is that DH never leaves his office some days, and he tends to work much longer hours than he would if he were in an office...it's hard for him to sign off and stop than it would be if he were 'going home' at the end of the day. This does tend to be an issue at times, and I have to remind him to take a break, go outside and take a walk, go for a ride to get out of the house, etc.
It's also nice for me though, because I can generally plan to go to Doctor's appointments, run errands, etc and not have to drag DS with me if he doesn't want to come. As long as DH isn't in an intense meeting, I can leave DS at home with him and run to my appointments.
And we usually eat lunch together every day (dinner is much harder because of kid's activities) with DS. DD is at school, so she isn't here for that, but we get some 'family time' during the day that other people don't get. It doesn't happen all the time, we always need to be flexible depending on what DH work is happening.
Another downside is that he deals with clients in India, Europe, the midwest, the west coast and occasionally, Australia. This is a

because he often has conference calls in the middle of the night, early in the morning, or late at night at odd hours depending on what client is the focus and what work is happening (when a new system upgrade is about to roll out, this gets crazy).
Overall, we like having him home in spite of the downsides. I'd miss him being at work everyday.
