Besides that, what do you (zx2c4) think of Linux? Do you think it's a safe platform?
I think it still has a long way to go. _Most_ programs require root access to install; and even ones that don't need root still have access to all user files. This is a but of problem.
Contrast this with iOS, where every app has local storage and one app cannot read another's files/data. On Linux & Android the problem of data security (among others) is persistent.
