Broke my computer

I was sitting in row 1 ( emergency row ) where you cant put you laptop under the seat in front of you because there is none ! So I put my lap top in the overhead baggage above me a few rows back only for the flight attendant to have over it with out me knowing, and when I get home, my hole screen in smashed !
