I think travelingmom and I have just had different expectations and experiences with the Euro Flight Bag. I got it to solve the problem of juggling three bags. I started using a CPAP several years ago. You can carry on a medical device as a third item, in addition to your carry-on bag and a personal item. The first couple of times I flew with the CPAP, I tried carrying the machine in the bag it came in, attempting, VERY unsuccessfully, to secure it to the handle of the RS rolling carry-on. Plus, I had the Civita bag over my shoulder. It was an ungainly arrangement to begin with, made much worse as the CPAP bag constantly flopped around atop the carry-on.
My current arrangement is to use the Euro bag to carry the CPAP, my camera wrapped in the otherwise empty Civita bag, my Kindle and stuff I want access to on the plane. So, two bags instead of three, and in my case, the Euro bag sits quite securely on the carry-on handle. Maybe I've packed the carry-on full enough to give the top some structure, but I've had good luck. And I like that the Euro bag is unstructured, as it will squish down easily in case anyone at the gate thinks it looks too big for a personal item. It slides under the seat on the plane with no problem. Also, those inside pockets that travelingmom has no use for are perfect for stowing the power supply, cords and mask for the CPAP.
Like the RS carry-on, the Euro bag has unexpected capacity. I've used it several times as on overnight bag with plenty of room to spare. My wife and I even shared the bag for a weekend trip once. I have carried my smallish laptop sometimes, but I don't want to lug it to Europe. I did a practice pack the other day with the CPAP, camera, etc., also adding my packable rain jacket and the Don't Tell Rick Bag, with those items wrapped in a pillowcase to serve as a makeshift travel pillow. All told the bag came in at about 10 lbs., which I hope to reduce with a travel-size CPAP before our trip in May.
My one knock on the Euro bag is that I don't find the shoulder strap terribly comfortable, especially if the bag is fairly heavy. Otherwise, I've been well-pleased and will put it to the overseas test on our May trip to Italy.
So, I think there's no right or wrong answer. You just have to figure out what's going to work for you. In any case, I now own the RS 20" rolling carry-on, the Euro Flight Bag and the Civita day bag. I find all of them to be functional, versatile and durable. No regrets on giving Rick the business.
