I ended up not getting the organizer, but did get the Cup Pilot. It has been on 3 trips with me since. From the first flight, not having to think about holding my coffee the whole time, or spilling my drink when I bump against the tray table- best $20 I've spent. Post-drink, it held my ipod handy, along with a few little items.
Thanks, guys! I still may do the organizer......
