My system is a tri-boot system. Windows 7, VL6 SOHO and VLocity (64-bit VL Beta).
VLocity? Now that is interesting to me. A 64bit port of Vectorlinux? I have been waiting for 2 years now for a 64bit version of vectorlinux . Seems it is going to happen soon.
Since all my machines are 4gig RAM with 64bit cpu architecture, I primarily run:
Archbang 64bit (What Vectorlinux was for slackware in the past; Archbang makes archlinux easy and fun)
Pinguy OS - Ubuntu 11.10 based (No crappy unity - a sane form of gnome 3; gorgeous in my opinion)
Spouse still runs her Ubuntu 10.04.
Friends with older PC hardware: Vectorlinux 6 xfce
I still check heere as this was a key starting point for me towards love of linux. This community was amazing and very creative.
