Hi Psynaptik! Hi AekiroStudio!
It's not in my mind at all, it's real in practice, when I use C2 and C3 in parallel to do exactly the same thing, everything is faster and more comfortable with C2. And this is not a question of habit either because C2 is very capricious too. It's a software reality.
Have you just read my hint about Photoshop or Unity (whatever) in a Chrome tab?
I have been working in development since 1998 (not counting studies and not counting my passion from childhood), I also managed teams, worked for very large companies and used a multitude of applications, I never took my hands out of the mud and I have always, like a fatality, been raised to quality services, whatever my job was and probably because of my sensitivity and expert eye.
Unfortunately, I don't have the chance to master English as if it were my native language - it's very difficult for me, even if I spend any day without reading it, listening it, writing it - to have as much nuance and humor as in French. I make a lot of effort because I understood that in game development, it is essential to master English, which puts an additional barrier to the rest of the world. It took me a long time to understand that Kyatric was French too, perhaps he may know (help me) what I really mean in these few big words.
Finally I am still, quite agree with what you say, my list, as indicated, was not exhaustive and is not delusional at all. It's just a pure reality. And you, as you underline here, are fair too: browser security, files/storage issues, new business model etc... are the reality too and real problems, not fantasy either, sorry to have forgotten to synthesize them in my answer.
In short, the comfort, in every way, and whatever you think, is not the same at all in the current state.
But I admit that C3 is a very beautiful jewel (<3), except that I still have to wait to switch permanently.
