> What POSIX stuff (it is just CLI and daemons anyway) can you really use for mobile apps?! It's not about POSIX per se - but among the Linux and Unix derived kernels, most of the things are similar. e.g., files are open with an open() syscall, file sharing semantics are mostly the same -- whereas on Windows, you call the differently-behaving OpenFile, and you can't delete or move an open file. Porting infrastructure (e.g. flutter) among POSIX-y kernels is much less work than porting to Win. > There Windows Phones are the only alternative for those that don't want to get an Android device. I thought Firefox phones were another alternative. Aren't they?
