they're easy to put in, anon.

if you don't experience inclement weather, it's probably not a big deal.

Storm doors are nice because you can leave the normal door open and use the screen to let fresh air in during the warmer seasons, or if it is super hot/cold it adds an air gap between the storm door and your normal door for added insulation and stopping drafts.

I would say they are necessary wherever you get snow
the temperature changes warp the wood frame and door so the door always has gaps, having 2 doors means there probably won't be snow coming in through that gap
I had a studio apartment in Buffalo NY with no storm door and I would have snow coming into my kitchen

I’d have to change my lockset every year until I got a storm door. The rust and corrode (white zinc oxide) inside and stop working, and water gets inside, melts in the day, freezes at night, and destroys the lock.
Now going on a decade with the same locks.
