That describes my situation precisely. I've been working on the amount of weight I carry, have moved on from my wheeled luggage (a trusty set from Air Canada that came with a lifetime warranty and is still going strong at over 10 years old) to an Aeronaut and couldn't be happier. Which is not to say that wheeled luggage doesn't suit most people. The only problem is weight restrictions - my carry-on suitcases have always been overpacked and probably weighed twice the allowed limit. But most airlines didn't use to care about the weight of carry-on luggage too much. That is now changing and to be able to bring more with me, I had to look for lighter bags, and lighter bags do not have wheels. It's as simple as that.When I first discovered Tom Bihn bags, I had a wheeled suitcase that I was happy with. It held enough, and it was convenient enough. Everyone else has wheeled luggage, so it seemed like the way to go.
But it was at this website (the forum or the FAQ, I don't remember) where I learned about the downsides of wheeled luggage -- the extra weight and the loss of space. And along the lines of OneBag.com, I was carrying too much.
It was a revelation for me.
I think the market is saturated with good wheeled options; Tom Bihn would be smarter to invest in lighter luggage...
