I use R regularly. I love it. Doing the maths is very easy and general. The programming makes me think differently. I like how it's high level, reasonably fast, rarely involves loops or inline functions directly, and, above all, is the Swiss army chainsaw of statistical analysis. The fact that the journal of statistical software exists is a good thing!
