Just to clarify, I'm not even comparing vinyl and CD.
I love vinyl and I'm sure I will continue to buy it and use it.
What I am saying is that having made the jump to digital it seems a bit retarded to try and shoehorn it into the vinyl interaction model.
When the motor car was invented, we didn't try to make it run on train tracks.
That said if you're hell bent on it (or you're a turntablist) then something like Serato or FS makes more sense to me than CD decks, and it's cheaper.
