I have large heavy devices (Provari) that I use when I am at home (I work from home). I will put a Provari in my pocket but so often a smaller device makes more sense.
I am always doing something that requires both hands so a Provari and a hands free device makes sense to me. In fact two classes of hands free devices are making sense to me. When hands are busy but nothing very athletic is going on an eGo sized auto is useable. Then doing something very athletic an auto cigalike is easier to manage.
I am currently trying to find the absolute best auto cigalike to use while I have a Provari in my pocket. Not one that will just do, the best that I can get.
