From your post it seems you're saying that because of this handy little bash script for screen you're scared of Linux ? You can almost always avoid using the command line in Linux, sometimes you will need to use it, for instance if you compile and install something ("./configure" "make" "make install" are the commands normally). Take a look at Ubuntu, or Fedora, totally GUI Desktop oriented, basically "Plug-and-play" hardware support and quick easy install. Don't judge the entire OS by the fact that the command line can be intimidating, the Windows CLI can be intimidating too, but you rarely use it I'm sure.
