Never really saw the point of all these spin-offs, when you can just either install GNOME 3 onto stock Ubuntu, or (if it's already installed), just log into a GNOME session. I guess it's for those who just don't want to have to download extra files.
Anyway, using Ubuntu on a virtual machine, it's pretty nice. The VMware tools don't seem to be working too well, yet, but hopefully an update will give me some smoother graphic performance and higher screen resolution. Beyond that, it works quite well, have no real complaints about it.
