I haven't had to use it in quite a while, but I remember having to use it all of the time in Chinook. Certain dependencies would always be missing from certain apps. Switching to Red Pill would make the dependencies available. Likewise, there used to be a number of "useful" things (e.g., Python bindings) that were only installable from Red Pill.

It was also fun to use just to see what was hidden there. I did a lot of "testing" on various libs and functionalities that way when I first got a tablet.

But, honestly, I haven't had to switch to Red Pill in over a year.
