I have three irons. This one I bought recently when I decided I needed automatic shut-off or I would burn the house down. Contrary to popular images, I wasn't loathe to spend money on something as pedestrian as an iron. I was looking forward to seeing what new features, in addition to the auto shut-off, I could have in a new iron. Actually, there weren't any. But it was still fun to go buy it.
Here is the one it replaced. This is a great iron, but it gets really hot. That makes it good for ironing lengths of fabric and shirts (Ha. Like I'd know.) but not so great for fusing and foiling. And any fabric that had too much finish on it would get scorched easily. So this one has been sent to live out its days in the laundry room, where its auto shut-off lets me have some peace of mind. I only iron clothes in a hurry, which is a recipe for forgetting to turn it off. I actually thought about having the outlet in the laundry room connected to the lightswitch, but I realized that it would be much cheaper to get another iron.
And here is the really old iron. Note the classic avocado green handle, dating it to the seventies. This was my mother's old iron, and I took it when she died. I keep it by the sewing machine for pressing seams and quick things like that, and it's connected to a power strip along with the lights and the machines. I don't worry about leaving it on anymore. And it reminds me of my mother, because once she looked in the laundry basket, took out the heirloom linens and gave all the rest of the stuff to Goodwill because she was sick of ironing it.
