As do I. Do you also bag the dust/hair/dander from the bagless vac? If you do, that solves the "all up in my face" issue, but if I'm going to bag the stuff from a bagless vac, I'd rather just start with the bag in the vac.
I don't want to go through the hassle of grabbing a bag, going outside, dumping the vac canister into the bag, dealing with the dust, tieing it off and tossing it in the can. Heck, I don't even like emptying my shop vac if it contains anything other than sawdust because of the dust it throws around! Again, that's just me. Again, I fault no one that doesn't mind doing that.
Again, if that works for you, that's great. It's just not for me. My shop floor has the sawdust while my garage is more for storage, an entrance into my side door and the occasional larger scale project if I need more room.
I don't recall "pretending" anything. However, I'm pretty sure that we can agree that changing bags is considerably less messy than dumping an open canister into a bag and/or a can. I haven't done the requisite testing, but I'm pretty sure the air quality in the general vicinity of a bagless vs. a bagged unit after a change/dump would vary considerably.
As I said before, I've tried both and I don't want to deal with a bagless. The rest of the world is free to make their own choices with absolutely no pushback from me. I'm not defending nor denegrating either type of vac. I'm simply talking about what I prefer.
