Some gyms have internet and e-mail access on bikes today.
You can also watch the news or catch up on the newspaper, but make sure you don't lose your focus and pedal too slowly. The recumbent bike does offer more back support but otherwise neither one is better than the other. It is a matter of personal preference. Make sure the seat height is correct. You want to make sure that when the pedal is at the lowest position that your leg is almost straight.
