I think for casual riding or commutting, clips with loose straps are still the best choice.

1. low cost (this is important for some of us)
2. Ease of entry and exit (of course this is negated if you tighten the straps)
3. Allow wide choice of shoes (I often use tennis shoes for short trips)
4. A large amount of float (more so than clipless in my opinion, negated with tightened straps)
