I can easily install new libraries and "apt-get source" allows me to tinker with existing software easily you can do the same thing on a mac, in a elegant way, so what's the advantage to do it on linux ? I use vim you can also use vim in a elegant mac terminal, what's the point here ? And stop comparing its competition negatively who was doing that ?
