We've had a Whirlpool Gold glasstop stove for a decade, at least. Handsome cooks like a madman on it, lol! We've never had any problems, and we use all kinds of different cookware, including a lot of cast iron, some antique.
Hot air for popcorn?! Say it ain't so! No flavor, might as well eat packing peanuts, IMO.
We use a Stir Crazy for popcorn, but I've made kettle corn several times in a regular dutch oven on the stovetop with plenty of shake, shake, shake action.
The only thing I'm scared to do is can on it, but some folks on the facebook Canning group page say they've done it many times with no problems. They suggested lifting the pot straight up when it's filled with heavy, hot water and filled jars, because the weight and heat would be enough to scratch or break the surface. I was going to get a propane burner just for canning this year, but since the garden didn't produce, I'll wait to shop for that off season.
The one thing I'll mention on the con side is that eventually black rings form around the heating elements that even with cooktop cleaner never fully come off. Aside from that, it's very easy to clean.
If I had my druthers, we'd get a gas stove. If you cook a lot like we do, it's the best way to go.
We have a ceramic top range we got several years ago. My wife cooks a lot and we haven't had any problems with it. The biggest thing is you do have to get some new pots and pans to go with it. They have to be perfectly flat (and stay that way) for the heat to transfer properly.
We don't make popcorn on it though. We have an air popper or use the microwave. I'm thinking someone must have invented a pan to do popcorn on them by now. If not maybe I better to get to work
You can get (a sample came with ours) a cleaning compound to clean it with. It's like rubbing compound for your car finish and it makes the top look absolutely new after you use it.
