When I was done using my MBA, I closed the lid and put it on chair because the table was full... About an hour later I go to sit down. I thought I sat on one of my sister's texts books from school, as I go to pull it out I discover it was my MBA. I completely forgot it was on the chair. Since I put all my weight on it I thought I broke the screen. Well... it was perfect, nothing happened. If this had to my previous Sony Vaio the screen would have definitely broken because it was so flexible. Great build quality !
