Glass can bend quite a bit more than that before cracking. In fact, just a firm Pencil or finger pressure bends glass on all iPads daily. If you don’t mind it visually (and it is hard to see, you probably wouldn’t even notice it without the table - and that is assuming the table itself is flat), you don’t need to worry. Also, don’t let the fearmongering on this forum prevent you from enjoying your purchase. And carry it around, that’s what it’s made for. As long as you don’t sit on it, it’s going to be fine.
You are correct, sir, however, glass is a finicky material. A close friend of mine is an extremely talented glass artist, and she is always explaining different dynamics of the material to me. While these thin glass screens do flex, and bend, and are forgiving to an extent, if the sheet of glass is continually under stress, from being flexed into a position it is not intended to be in, due to a bend in the iPad chassis, it will take significantly less force, or torque to cause it to crack and/or shatter, than it would have had the sheet of screen glass been continually in its unstressed position. This is the concern I was gearing my post towards.
