May I ask what were your reasons for moving from Windows to Linux OS?
Because it fully customizable and with much better font rendering. Many other aspects just a details, which always bring people to holy wars

What edition do you use?
ArchLinux with GNOME 3 in fall-back mode(classic mode in other words).

How is the stability and driver support?
Everything just works for me(except ATI drivers, which are crappy as in Windows, but fortunately in Linux I have open source realization), in many cases without a need to search drivers over all internet, as it was today at work for my LG Optimus One(Windows 7 wasn't able to connect it for developing).
