As much as I want XFCE 4.8 I know that Texstar has our best interests in mind in not it being available in Updates at this particular point in time. Yeah watch (with my lack of luck:)) within a day or two a 2011.06 or 07 XFCE Phoenix Edition with XFCE 4.8 will be released - lol!
Good things take time and effort in which Texstar and his development group donate so then we can enjoy the fruits of such is how I see it.
One thing that "puzzles" me is why PCLinuxOS is not higher up in the Distrowatch standings than it is?
Maybe some people only love .deb distros?
Anyway, we know what great a distro family is PCLinuxOS.
