This is probably just a personal quirk, but I despise spiral bindings. I hate the feel of them. They never hold together. They catch on everything and come apart. Pages get torn far more easily. They make the books - if you can even call spiral-bound stacks if paper that - more difficult to organize. They suck.

I hate my non-spiral bound music books - they never sit well on a music stand. However for all other books I agree, spiral sucks.
