OK, OK. I'm not sure "this fad" will ever go away. Maybe we'll get better screens less prone to fingerprints, but even then, why is your screen getting so dirty anyway? If you're eating cheezies (Canadian thing) while you're using your tablet, you're doing it wrong. I've been using Android devices for about 3 years now, and with every device, the screen's brightness made up for any fingerprint issues.
And on the tactile response front, it's called haptic feedback. Your device shakes a little when you press a button. There's no way that glasses and gloves will take over from current touchscreens, unless the whole world decides they want to look like complete dorks all the time. Granted, I welcome looking like a dork, but my wife will probably object the next time we go to a party.
