Well, desktop linux rarely forces you to use terminal and I prefer not to use it on mobile phone (typing on small device sucks) but I miss some desktop features. For example, on desktop I can force most apps to use proxy server via proxychains util, Android doesn't allow things like that. Or on desktop I can mount a remote directory via sshfs so that it acts like a regular directory for all apps. On desktop I can launch multiple instances of browser with separated profiles.But I understand that "do whatever you want" platforms are not possible to make popular, most people will have problems with it..
