At home: road bike (Look), touring bike (spd), ATB (spd) and Folder (platform - soon to be spd).
On tour: I leave the spd pedals at home and put on pedals with clips. My theory is that if anything goes slightly awry on the road I can sort out a clip/strap more than a faulty spd. Furthermore, I do not like walking around with spd clips, nor do I want to tour with an extra pair of shoes for walking.
