Having been an R user for about 10 years (mostly as a student), I've always considered it more of a "programming language" than a pure statistical package.  For instance, teaching an intro statistics course to non-technical students using R is a nightmare.  But it was perfect for thesis work.  I also use it often for parsing text (having never learned perl).

This is the line I give people regarding R:  It's easy to do difficult things but hard to do simple things.
