I also have a Schwinn Airdyne. The computer part did fail on my after 10 years, but I bought a new one for $70 at a local bike shop. I like it because it blows air, it lets me use my upper body as honeybunch says, and it's very simple. I use it 2 or 3 times a month for a cardio workout. I often pop in IntervalMax or Gin Miller's Intense Moves and do intervals when the tape does. It is a great workout. I end up riding about 12 miles with Gin Miller. I stop Cathe around interval 9 at 12 miles and cool down a bit, the warm-up is quite long on IMax for following with the bike. Anyway, it's a great option to have. It really builds legs and cardiovascular capacity while not stressing my knees much at all.
