Call me crazy, but I don't mind the airline food. One of the biggest kickers for me is whether or not the flight is serving breakfast/lunch/dinner in F. That makes the e500s a no brainer for me. I really like NOT having to worry about a meal as I travel way too much (although probably about average for those of us on FT!).

My seat location and whether I have an empty seat next to me, or not, also plays a big deal.

Otherwise, I almost always use them on any flight <500 miles.
