PLEASE Lower your seat back SLOWLY!!
I have a real simple request (and I hope everyone can pass this on). If you want to lean back your seat on the plane...please feel free to do so. BUT PLEASE do it slowly!! I've almost had my laptop broken twice from someone in front just pushing the button and slamming their seat back. The top of my laptop gets stuck in the tray table "lock" area and just about snaps it off. (One of my colleagues actually had their screen broken a few months ago.)
I'm perfectly OK if you'd like to be comfortable...please do so with regards to others around you!!
