I don't see it as all that complicated. Sure, there is a learning curve to find the equipment and juice that works for you, but once you have it figured out it isn't that bad.
When I smoked a pipe, I didn't own just one pipe (and pipes weren't cheap). I remember the quest for the right pipe tobacco and waiting for the postman to bring me something new. When I went out, I had to bring the pipe, a pouch of tobacco, a pipe tool, pipe cleaners, and at least one lighter. When I smoked cigarettes, I tried all of the different brands never left home without a spare pack and spare lighters.
Now, I just tuck my little Vmod in my pocket. I have a little kit with spare battery, spare atty, and a spare bottle of juice that is about the size of a pack of cigarettes. When a bottle is empty, I just fill it. It really isn't much more complicated than the old days.
