In this weeks edition of DWN, they have a review of SimplyMEPIS and a comment to Ubuntu not including 3D desktop per default.
The Review states:
I'm sorry to report the hard drive installer failed on two different machines with several combinations of factors. The only common factor between the two was the NVIDIA graphics chip. There was nothing I could do to convince the installer to finish. It stopped and the whole system stopped responding at 85%. Since this system is still in beta, we aren't going to hold that against it at this point. For now SimplyMEPIS is looking good and holds a lot of promise for this upcoming release.
