Tokyo salaryman reporting in.
This is definitely the next career move for me if I stay corporate. I waste about 3 hours of potentially productive time each day -- not to mention the wind-up time necessary when sitting down to work.
1 hour morning prep to go out, 1 hour commute each way on central Toyko trains, and 30 odd minutes settling in at the office. Only to do exactly what I could be doing at home...At this point, I think telling developers the benefits of remote work is preaching to the choir.
