I've finally found a bag which nicely fits almost everything I want to carry every day, and alos makes everything easily accessible - it is about the same size as what I used to carry, but now I no longer need to dump everything out to find what I neede, even with some lose parts still in there.

Many years ago I've now and then searched for bags for throwing in all my electronics - but seems back then having that need wasn't mainstream enough. When I got frustrated recently and searched amazon again I noticed that nowadays there's a wide variety of bag designed for that purpose, with different levels of usefulness (plus the simple ones copied/rebranded a lot). So, I just ordered one of every somewhat sensible looking bag to figure out later what is useful for which purpose.
This particular bag is the Inateck AB03007-S, which turned out to be perfect for my daily stuff.
