Pro: the primary benefit that is touted is that it supposedly reduces the dead spot under the boot in ski flexion. A more obvious benefit of the Fluid system is that the bindings can be easily adjusted and re-adjusted for any boot size without having to re-drill. This helps with resale value. Also, you can tweak binding fore-aft positioning. Something that is not obvious to many is that the Fluid system fixes the excessive delta (~6mm) of the flat PX bindings to the more common/modern delta of ~2mm. The system is not terribly complicated, so doesn't add that much weight to the ski.
Con: Depending on the model, I have noticed a bit of play to the binding/track interface when assessed by hand. My Legend 8000 Fluid, which has a plastic rail, has a noticeable amount of play. My Contact 10, which has an aluminum rail, has no noticeable play. I didn't notice any play with the Contact 4x4 I had demoed, either. I don't notice any play with any of these skis while skiing, though. Also, the ease with which the bindings can be adjusted makes me more paranoid about theft, so I lock up my skis. Obviously, the Fluid system only allows Dynastar (Look) bindings. While these are great bindings, they are on the heavy side, and you may have specific needs that may require a flat ski (such as wanting a touring option).
