I stopped using Windows as my primary operating system about two years ago, making the switch to Ubuntu on all my work machines. My coding environment of choice for R is GTK Emacs with ESS, which both install almost by themselves through the Ubuntu setup.
Because I've been off Windows systems, I haven't given much thought toward using REvolution's version of R, which had as its biggest selling point the use of fancier compilers to speed up run time (not an issue when it builds from source on a Linux machine). However, the newest release of Ubuntu ("Karmic Koala") has revolution-r as an option, complete with their mechanism for parallelizing R code. So it's finally worth a go from my end, especially on my four-core-eight-thread work machine. Next project I code, I try it in revolution-r.
