BlackBerry OS 10 was my favourite one. They way it used widgets and gestures was really cool. Hub application was awesome. Android and iOS copied a lot of it later but I liked how simple and minimalistic BBOS10 was compared to them. Never tried developing for it though.
In my experience writing functions is easy and using LLMs for it is a waist of time. I would spend more time adapting the output to my code and making sure it works fine. What I could really use help with is figuring out how to use some more advanced features of some tools/libraries and so far the tools I’ve tried fail at this completely.
Downfall? It has 150M active users today.
People talk about FFOS like it was a failed project while in reality it was successfully commercialized and is so popular it has a native WhatsApp client. It has ~70x more users than LineageOS. Maybe Mozilla didn’t knew how to make money out of it but it’s definitely was a great OS project.
But that was the old OS, right? Not the BB 10? I’m talking about phones like Q10, they were completely different from the old phones with cursors.
