It is surprisingly hard to run Android apps on Linux, despite Android itself being Linux based. Being able to run Android apps quickly and natively would be a game changer for Linux, resolving long standing issues of app availability. Hell you could even then use Android version of Microsoft Office etc. This should be a higher priority for all distros.
Until then, there are apps that are simply unavailable on Linux, even with Wine support, that necessitate using Windows or macOS.
I frequented Cape Town and Johannesburg doing research, that also included going into black townships to chat with people. I myself had an escort of 15 huge guys with guns and still had all sorts of problems around Nyanga including a shoot out over me recording video. Would never walk or drive around there on my own, I saw so many tourists and (white) locals being targeted, attacked and beaten on the street. There's a reason everyone lives in highly secure compounds. You should know this before going to SA. The most beautiful place, best food on the planet, but you may die for it.
