- Image installers (.dmg files) and complete installers (.pkg files, that bring dependencies with them). I have never seen either of those fail, ever. I have seen installations from .tar.gz -> ./configure && make && make install fail countless times. This is the number one reason for me, and it's so much more important than anything else that I have trouble thinking of other reasons. I absolutely dislike the model that linux package managers use to handle dependencies and I do believe in bringing all libraries/dependencies needed with the installer and compiling them with disable-shared on. To do otherwise is to suffer a whole day trying to install ImageMagick when it should be a one-click task.
- Any other reasons pale in comparison to the first reason. I guess it's nice to have decent trackpad gestures... but I'd forgo everything for easy installers that bring dependencies with them.
