I ain't cooking a 70-100 dollar piece of meat without knowing its exact temperature.
Think about it. Just 10 degrees and I have a medium prime rib instead of medium-rare. Oh the humanity!!!!
What they really need to make is a remote with another sensor that reads internal temperature of the grill.
A thermo isn't needed for steaks/small stuff. But ain't no way I'm overcooking a big beef/port loin or other sumptous cut.
And given that they can take hours to cook I like the remote aspect. I may just pick one up.
