Train

Pros
I can use the Wifi on the train, which means a solid hour of uninterrupted typing.
It's nice to get out and walk every day because I need to walk and work just doesn't let me out during a day.
People talk to me more, reminding me that I live in a large if suburban city.
My brain sometimes believes we're in England because we're using non-horrifying public transportation.

Cons
It takes an hour to get home.
It takes forever to get on the Wifi.
Train cars are small and it is hard to share a seat and type.
I have to cross Bascom, which is not so scary after crossing MG Road in Bangalore, but that's not a decent basis for comparison.
