Personally, I spend more time cycling than I do watching TV, but YMMV. I bought my Brompton to ride to the office, so I wouldn't have to leave a bike outside. A few weeks after I bought the bike the office building installed bike lockers in the parking garage. I rented one and switched to commuting on a non-folder. I don't regret buying the folding bike though. I use it when I drop my car at the shop for repairs and then ride to the office. I also take it on road trips. It doesn't take up much room in the back of my Subaru wagon.
