Apple researching glass keyboard for strength and transparency
Future Apple keyboards may feature keycaps that are a mixture of a glass top and color backlighting, for longer-lasting keys which could potentially be used as mini displays.
If you’ve been using Apple gear for long enough, you know that they are always hard-wearing, and that they always last many years. However, you’ll also know that the first thing to show wear is the keyboard. The letter legends on the keys eventually rub off, and at times the keys themselves wear out.
