As a power user, I don't really feel I have particular unfilled needs in any Linux environment. Most of what I need, development-wise, I already have. All that requires is a shell and the ability to configure my apt sources. That said, I don't do much OS-level anything. For that, you will probably always need a distro that assumes less about your graphical environment. What I do miss from other OSes/environments is that sense of a tighter integration. I spent many years not missing it, having originally gotten into GNU/Linux by cobbling together my own crummy environment in Gentoo (on which Sabayon is based). It wasn't really until I first tried Windows 7 a few years back that I realized that if I actually wanted to use the latest this-or-that application in a seamless (dare I say enjoyable?) manner I needed to stop clinging to my obscure WMs. And yet, to this day, I'm actually still clinging.
