As for the fragility of the screen - after hearing all the horrendous stories I've become paranoid. I never sit down unless I check the spot where I'm gonna sit(no matter where I am). I handle my C. as if it was a WW2 grenade. I never put anything on top. I put it where I can see it so I don't sit on it accidentally. They really need to start makin em sturdier, coz this is not healthy.
That reminds me that I should put some padding on the floors.
