Pretty neat if you have a box of tissues to stow, not sure it's useful for the offending items that cause the overhead scrum.....oversized trolley and shopping bags. The overhead bins aren't usually teeming with iPads and laptops without carry cases.
At the end of the day the real overhead solver is this.....properly police carry-on luggage to prevent people from bringing chandeliers, piles of books, wide screen TV's and trolley bags filled with house bricks onboard. Yes I've seen all of those. Or even better, remove the overhead bins altogether. Sorry sir, you'll either have to check that bag or cancel your ticket. There is only underseat stowage on this aircraft.
The problem isn't with aircraft it's with people, who refuse to follow the rules believing that they are the sole exception in all the universe to them. There isn't an overhead compartment that can compensate for human stupidity and selfishness.
