Pros: handling, sensor, L-mount, menu, preset filters (really not negligible, well thought out and customizable), design.

Cons: The only real flaw is the lack of a second slit for the shoulder strap, forcing you to mount the Peak Design cleat underneath or hold a wrist strap. - Battery lasts short - lack of real pancakes

Opinion: Spectacular car, at least for me. I was lucky enough to receive it in Tokyo during the presentation and, after a few months of use, I can say that it represents a completely different concept of camera, and this is the thing I appreciate the most. The criticisms that have been leveled at you, in my opinion, should be scaled down after real use in the field. 1. Absent viewfinder: for a young and non-professional audience, it is not a problem at all. I come from the world of professional photography and I understand its importance in certain areas, but those who choose this camera do not do so for work use. If you think you're using it professionally, you're probably looking at the wrong product. 2. Built-in memory: Great choice. It is easier and more immediate to connect the machine via USB-C (now standard everywhere) and access photos directly, even from iPhone. I never ran out of space, even shooting in RAW. On the road I lost tickets several times or I forgot the reader: here this problem does not arise. 3. Fixed screen: it might seem like a limitation, but personally I have never had the need to tilt it. I imagine that the choice was also dictated by the aluminum unibody construction, which makes it difficult to integrate a mobile mechanism without increasing costs. 4. Battery: yes, it doesn't last long. But it charges like a smartphone, even from a powerbank, so the problem is easily circumvented. Just have a spare battery if you plan to use it heavily. 5. Touchscreen and menus: touch is not active everywhere, but the menus are so simple and direct that you will immediately learn how to use them. It's all designed for a non-technical audience, and that's why it's quick to manage. 6. The IBIS is missing: true, but it is not a machine designed for video. It holds up well to high ISOs, mounts the classic 24MP Sony sensor and, after using it, I can say that in the vast majority of situations it is not needed. Adding it would only drive up the price even further. 7. A single ring: here too, a consistent choice. It is enough if you understand how the interface works. It's not a machine for professionals, and it doesn't want to be. 8. No flash shoe: I never felt like a lack. If I need the flash, I use another camera. 9. Electronic shutter: some see it as a limit, but introducing a mechanical would only have complicated the construction without bringing real benefits for the users it is aimed at. It is a machine clearly designed for young people, accustomed to smartphones, who want to move on to something more serious but simple. I myself made my girlfriend try it: she is not a photographer, but she has some basis. She usually shoots with the iPhone, but she immediately got along very well with it. For you, it's perfect: excellent quality, intuitive operation and beautiful design. This camera has everything to become an icon, or at least the beginning of a new iconic line. I understand the criticism of those looking for pro characteristics, but I invite everyone to look at it with different eyes, those of those approaching photography for the first time. That's how I lived it, and that's how I'm enjoying it every day.
