XP Pro and OpenSuse 10.3 dual Boot on my personal laptop.
XP Pro and Mandriva Free 2008 dual boot on a work laptop.
XP Pro and Sabayon 3.4f dual boot a work Dell 380 desktop.
Plus I keep playing with another set of LiveCDs such as
PCLOS, SimplyMepis, eLive, OpenGEU.
Wish I could put my mind more into Linux and CLI
than being stuck with MS Windows and GUI
But, OpenSuse got my vote since I was an early adapter of
Suse from the 9.0 days before Novell grabbed it.
