Whenever you have a bad posture people are quick to point it out but when people see a chromebook with a bad stature no one says anything. If you keep your chromebook at an obtuse angle then it would have a change to completely break the screen if anything hits it and if you keep it at a acute angle then it has a chance to close the chromebook.If you keep your chromebook is at a 90 degree angle then nothing would be able to break it or close it.
