This isn't targetted at the experienced cook. It's targetted at somebody with limited experience cooking who wants a little more probability at success. My internal geek is fascinated by it, and I'd buy it if I had the spare cash lying around, but my internal cook sees its applicability limited (though perfect salmon every time is tempting; I'm not that great with fish).

It's unfortunate that the generational tradition of teaching cooking really fell apart in the last 40-50 years. My generation was the first who had to completely teach themselves.
