Too "hands off" for me. I enjoy brewing more than drinking and I like to have my hands in every aspect. This seems to me to be more of a coffee pot. Put your grounds in, add water and turn it on. Plus, more than brewing, I enjoy building 90% of my equipment.
I get this. Although my base approach and technique have always followed Denny's cheap n' easy set-up and process, my unique modifications and tools and improvisations, and built-by-me equipment come together to satisfy my creative side to hit numbers, make better and better beers, and feel like I'm not following the same manual as the thousands of people who buy a designed and mass-produced system with parts that may or may not limit what I can brew in at least a full 5-gal batch. That said, many designed systems make me drool, and the efficiencies and control they offer definitely provide a greater range of control than I have with my system.
I definitely would consider a Grainfather if I didn't have ample room to store multiple propane burners, keggles, picnic cooler mash/lautertuns, yadda-yadda-yadda. Gee, I'm a lucky, if somewhat frugal and engineering-deficit guy!
