^^^This.

My wife has a Salsa Shaft on both of her bikes, and every time she has to tweak her saddle -- which she used to do constantly 'cuz she was screwing around with her position, but now that I think of it, she must be pretty dialed in 'cuz I haven't seen her messing with anything lately. Oh, sorry, I digress --

Every time I watched her tweak the saddle angle with that cool wrench-activated cam, I'd think "Why couldn't every seatpost be as cool as that?"
