One of the issues of working from home is that you track your hours more closely. So where as in an office if you're only productive for 5-6 hours it's not tracked and so people probably won't notice. If you work from home your expected to be productive for 7-8 hours a day. This can mean working 2-3 extra hours that typically you'd save in commuting.

I don't see myself as being particularly more productive at home. I charge by the hour and so financially it doesn't make sense to commute and pay for an office, but for anyone who's getting a fixed wage I think the commuting benefits can be over stated. The main gain is in flexibility.
