_FAN pretty much nailed it. seems gross to me for most meat because you're not getting any carmelization of the sugars in the meat/crust but i would def try fish cooked sous vide. tbh, it's similar to any other style of slow cooking (crock pot, smoking) except every area of the outside of the meat is exposed to the exact same temp like fan said as opposed to heat variances/hot spots that exist throughout the crock pot or smoker.
they use the method on Iron Chef America all the time. would be somewhat similar to pete's tailgate omelet things.
