Finally an airline does it right! Larger overhead bin

Having had a heavy object dropped on my head from an overhead bin, not sure I like the sound of this.  More space is good, but filling an over-our-heads space with ever more large objects, given the certainty of gravity, I'm not so sure.  

Larger carry-ons won't be allowed.  Just more of them.  If you are among the last folks on a long flight (say to Hawaii) now, your carry-on will be checked as there is not enough bin space.  

People need to be cautious about taking stuff out of a bin -- that doesn't change with more or less bags in them.
