the duffel bag holds more.
the backpack is easier to carry.
the duffel bag has been through baggage check many times and is a little worn in places.
the backpack has no visible weak points.
the duffle bag is just one big compartment: every sock for himself.
the backpack has little compartments for all sorts of categories of objects.
this is complicated by the possible choice of the small rollaway bag which
looks dorky being hauled down mission street.
is also worn from many trips through baggage check and initial cheapness.
doesn't hold any more than the duffle bag but has hard sides.
when not rolling is difficult to carry.
I'm leaning towards the duffel bag. I wonder what the chances are of its zipper failing and my dirty laundry being blown across the tarmac. I could wrap a couple of straps around it for greater stability.
there's no question as to which bag my books will be in. the checked bag. if I am lucid enough to read onboard the aircraft I will be too busy panicking to read. if I am relaxed enough to read, reading will put me to sleep. I think the ipod will be my friend in fact I ought to download some daily shows to watch. let me see if I can get itunes not to crash when accessing the music store. it almost always crashes and I don't know what the problem is and there are no simple cures anywhere on any of the mac boards that I've looked at.
then I think I will meditate and go to bed and do everything else that needs doing between 6am and 11.
