Each aisle in the supermarket has 100s of things that I'll never buy, but there's a green eyeshade guy somewhere ensuring the revenue per linear foot of shelf space stays high. Someone is buying it. It works for someone.

For me, personally, I'm not buying:

• that clips with tightened straps are easier to get out of than clipless (on an absolute scale, presuming you've made an equal effort to learn both systems; relative differences for an individual may abound)
• that a secure connection from foot to pedal is not more efficient than platforms
• that those little orphaned strapless clips do anything other than say "put foot here". Do they also say "left" and "right"?
• that learning to do wheelies (manuals) in clips is a good idea
• that anything works for everybody all the time
