re: Glass Cooktops - How Fragile are they?

Mom and Dad had one in AR. I learned what a PITA the black glass is to keep really clean.

Every meal with any kind of grease/butter/oil, every tiny splatter showed.

I learned a routine of soapy sponge, water sponge, dry sponge, water sponge again, dry sponge, buff with fine cloth to keep it looking good. This was after EVERY use!

If you are planning to keep the glass looking good it's gonna be a LOT of manual labor. It did look almost brand new when we sold the house though.
