Tux Machines (TM)-specific
A trio of alpha releases have hit the virtual streets; Ubuntu 8.04 Alpha 4 February 2nd, Fedora 9 Alpha 1 the 5th, and openSUSE 11 Alpha 2 the 8th. And, yes, they are indeed alphas.
Ubuntu 8.04 Alpha 4, Hardy Heron
The most mature of the early releases. I've burned and booted both Ubuntu since it's been my experience that the KDE version of Ubuntu (Kubuntu) is the weakest KDE distribution I've ever experienced.
Fedora 9 Alpha 1
Fedora 9, as did Fedora 8, comes stumbling out of the development gate and onto my systems. It quickly became evident that Fedora 9 Alpha 1 would not boot to the graphical desktop on any of my systems that contained an ATI graphics chip. If they contained an nVidia graphics system then they would come up - slowly. I downloaded and booted both live ISOs, both the Gnome and KDE 4.
