Hi! I have a new iMac 27 retina, and i notice that when i wright fast with my both hands i notice a small wobble/shaking on the iMac screen. I think its normal since it feels just like my last 27" late 2013 iMac. If someone goes by and bump into the side of the table or something the iMac get more wobbling/shaking, is it made for this kind of stuff? How solid is the foot? I guess many other have the same "issues" that if someone is into your table or goes by and bump into it then the iMac shake from side to side? Could this be a problem in the future? Is it solid and made to last even if it not stand still all the time? feels felksibel only if you barely touch it too.
