Question for those in the know: of what use is a screen protector for a glass screen, as with the Jolla tablet? I've kept a protector on my N900s from the beginning, as I see the value in keeping a shield between sharp objects and the plastic resistive screen; but I'd think that a glass screen really isn't going to scratch all that easily. And any impact strong enough to crack the screen isn't going to be stopped by a thin layer of plastic...

So, basically, is there any advantage to having a screen protector in this case? Thanks!
