I love riding the bike. I think if I had access to a car and *could* drive to work, I wouldn't, even if it meant more sleep. In fact, I dropped out of a car "pool" (I paid a share of gas and toll expenses) during a job last summer just so I could ride (and yes it took longer to ride!).
I, too, like to use the computer. If my commute is mostly a steady ride, I try to beat my best times, etc. The latest job involves riding through Midtown Manhattan, though, so the competitive aspect is shed in favor of surival.
