For me, it comes down to simplicity. Integrated this and that sounds nice at first, but the trade offs in space and weight usually are not balanced by the convenience that often fades as soon as your device changes. I am more curious about the removable wheels - what do you do with them when you take them off?

Having said that, I think that if a designer can come up with a really innovative wheel and handle design that takes up a minimum amount of capacity that would be a huge selling bonus. I don't want to many storage compartments - that again means less flexibility in packing room, but ideas such as storage for a water bottle, boarding passes, cell phones and wallets while going through security, etc. are valuable features.

Thank you for taking such an interest in feedback. I hope the bag turns out well.
