I agree with every single one of those points. Other thing I'd meant to mention, was that the territory of "wheeled luggage" has expanded. Previously maybe at an airport you'd haul your luggage to a car at the kerb that will take you to your destination. Modern airport usually has some public transport that takes you into town, and from there you get further transport to where you wish to go. i.e. Having your luggage be less of a burden opens up your choices. I live in a university town with a lot of foreign students. It's now entirely normal for me to see one 'herding' (for want of a better word) a flock of cases quite successfully down the pavement infront of me.
