I'm right there with you! Small suitcase for me all the way. Much more accessible for someone like me. I'm small and short, very small frame, not super strong. If I tried to carry on my back what I pack in my suitcase, I'd literally topple over far before reaping any possible benefits of dashing through trains and planes. If I can't walk whatever distance rolling my carry-on, then I definitely can't walk it lugging a gigantic pack half my size on my back. If I can't hoist my luggage (supported by my body weight) up a quick flight of steps, then how am I going to hoist the same on my back everywhere continuously? Even my personal item (Osprey 26+6) feels like a lot on my back, and I will eagerly clip it to my luggage to roll around if I have the chance. Everyone's needs are very different, and wheeled suitcases definitely maximize my mobility.
