I’ve seen tray-top stands to hold your mobile devices during flights, but they always seemed a little dangerous to me. Because they weren’t tied down in any way, it seemed that your mobile device could go flying in case of turbulence. The cradle of the Skyview Seatback Mount for Mobile Devices holds mobile smart phones, tablets, and eBook readers up to 5.25″ X 8″. Its base fits over the setback tray latch and grips securely to keep your device from taking its own flight. It works with seats found on most planes, trains, and buses, and it can even work as a tabletop stand. The Skyview Seatback Mount for Mobile Devices is $29.99 at Griffin.
