I guess it's just personal preference, when it comes right down to it. I like a viewfinder for those times when seeing the display is difficult. I used to use the Canon G series, but am a Nikon guy at heart. The Nikon P7000 has everything I want in a P&S....Nikon discontinued the viewfinder on the newer P7700.

The sensor size difference between a P&S and DSLR also indirectly affects the depth of field options you have. The P&S with much shorter focal lengths can't blur a distracting background near as effectively as the large sensor and longer focal lengths of the DSLR.

Still wouldn't like to carry one while riding, though! Too much size and weight, and too much of a possible financial loss in bad weather, or in a fall. The P7000 fits nicely in a case on my belt with my phone and ID's.
