I agree.
Carry on baggage (except your computer or purse) is SOOOO annoying and causes most of the delays.
(Ok, I do have to say when I travel with the grandkids I carry on a bag with books, games, snacks plus electronics).
I will gladly pay extra if I need to for that.........for my own sanity and that of the rest of the plane. ;-)
I have long been of the opinion that they should allow those of us who can just get up and go (without opening the overhead bins) to get off the plane first - my policy was to check all my luggage and I had nothing with me but a pillow with a couple books shoved in the pillow case.
When they started charging only for checked luggage I saw the ridiculous amounts of carry on luggage go straight to preposterous levels of excess.
