I think Sabayon has a lot going for it, not the least of which is a *beautiful* look. It's definitely the prettiest distro I've ever seen. Unfortunately, I spent over a week trying to upgrade all the packages in "world", and it was a headache. I never did finish upgrading (in 10 days!). Instead I moved on to try other distros. Not sure if upgrade hell is Sabayon's fault or Gentoo's, but it's Sabayon's responsibility to make things go smoother. If the problem stems from Gentoo, then Sabayon needs to evolve more and be less dependant on its parent distro.
