Yes, you are correct it was the C182P, it does have cannards. I mentioned before that some manufacturers believe a well designed wingtip does not need winglets. This is not to say that wings with winglets are poorly designed.
As FE hoppy has said, wing design is a compromise. Winglets give the biggest advantage to long range aircraft, which fly at relatively constant speed. However short haul a/c can still benefit, but not to the same degree as their long range counterparts. The other reason for winglets is to reduce wing span, ideal for a/c which have trouble fitting into gates.
