Steel is a lot heavier and a lot weaker than carbon fiber. For you that's an advantage, but not for those of us who use our keyboards on trains, in cafés, in hostels, and in tents. The comforting weight of an IBM Type M keyboard gets old fast when it's stuffed in your backpack on a bike.
That probably also helps explain how we break keyboards.
Ah, okay. To me that's what my laptop keyboard is for, but I think I understand better now.
If I did need a stronger keyboard, I'd rather have it reinforced with steel. That would have the extra benefit of keeping it in place.
