I am a Maemo user. I have 2 Linux desktops (one at work, and one at home). I am not in a programming, development environment at all. But Linux makes makes life a lot easier for some of the things that I do, esp at work. I'm fairly comfortable with command line, but am no expert. I am a Maemo fan though, and that has been fruitful for me, in terms of exposing me to new technologies, a rich user community (t.m.o) and most recently, by the gratiousness of Maemo Devices - sponsorship to the Maemo Summit in Amsterdam. This community is simply amazing - don't be afraid to be a Fan!
