Granted, I have a short commute and do not have a bike with rack or fender mounts. I have no plans to buy myself a new bike any time soon, especially since i just bought my son a new bike.
If you have a long commute, like over an hour, that backpack against your back is going to be one sticky mess of sweat on you backside. On my 50-60 minute commute I begin to feel the sweat on my back at about the 30 minute mark if I'm wearing a backpack, but without the backpack I can make it all the way without much sweat on the back. That the difference.
I do have a bike with rack and panniers, but I find it to be too much of an aerodynamic drag. I'll only use it when I have loads to carry, and even then I'll still wear my backpack.
