You realize your computer won’t work without scripts, don’t you? And if you want your computer to do something it doesn’t do on its own, a simple script will make it do what you want. If that is your definition of sucking, then you need to go back to Windows, which is also loaded with scripts, by the way, so that sucks too.
It can be much easier to install a PPA than using the command line to do so. I think it’s high time it was as easy as clicking on a (verified) “install this repo” type button on a page, and confirming, entering your sudo password from the launchpad website. I’d even be OK with building it into Discover.
