Not convinced, he's not pressing hard at all. I used to sell appliances and often did the key test to stoves to show people that glass top stoves are strong as heck. If you push moderately hard you'll leave a trail of microscopic metal filings on the stove. I'll look like you wrote on it with gold chalk. In other words, he's not pushing hard at all, he's simply glossing the key over the screen.
Before you bash me, yes I'm buying this phone and yes I think their glass will be very tough. I just don't think this is a proper test of that glass. When I go to the store, I'll do a 'proper' key test on the store display.
