It does take time but it's time I usually spend about 15 feet away from the smoker sitting on the coach drinking and watching games.
The only stuff that takes a long long time is brisket and pulled pork/pork shoulder. Those both take overnight. I did a brisket on Friday night that I started around 11:30pm. I stayed up drinking as long as I could and fell asleep around 2am. It's not really a big deal.
Whole chickens, ribs, sausages, fish, etc can all be done in during an afternoon of yard work, football game watching, yada yada.
It's fun though, I think you'll like it. Each time I light my smoker up, I learn something new and get better at it.
