This may have been discussed many, many times on this forum before, but based on the number of responses in such a short time, it sure is still a hot topic among cyclists!

Strictly speaking about bicycle commuting, my response is "not." I don't use clipless pedals for any type of riding, but I can see where some long-distance cyclists might like them for pounding away at the road and/or hill-climbing. For the type of stop-and-go involved in my personal commute, I sooooo much prefer simple platforms. My reasons are the same as those already provided by others.
