Oh, and Crankbrothers Eggbeater pedals!
Nominally they are mountain bike pedals but after trying several different clipless systems for my commuting and recreational road cycling back in the day I decided they are the best for my usage too, and have put them on every bike I've owned since.
The key for me is the ease of clipping in and out, especially the clipping in. Because you can clip in from any of the four sides of the pedal there is no need to fiddle around making sure it's in the right orientation when setting off, you just push down and go. Bonus, they use two hole recessed cleats so you can use MTB or, better still, cycle trekking shoes and actually walk around when you get off the bike. Another bonus, the pedals need no adjustments and (almost) no maintenance.
