I really love my Samsonite "mobile office" spinner. I don't think they make that specific one anymore, but they do make similarly nice-looking bags.
I find that the one-shoulder totes can make my back hurt when weighed down. I am either going to use a backpack with organization options...or an under seat suitcase, that can double as a mini filing cabinet: https://www.amazon.com/Samsonite-Luggage-Womens-Spinner-Mobile/dp/B00GI3572E/ref=sr_1_29?crid=2SCLILA83UZ47&keywords=underseat%2Bluggage%2Bwith%2Bwheels&qid=1561556619&s=gateway&sprefix=under%2Bseat%2B%2Caps%2C184&sr=8-29&th=1
