The launch of openSUSE 11.0 was a big success and positive reviews keep showing up :-), two especially nice ones:

ars technica: This is a very strong OpenSUSE release with a lot of compelling improvements. OpenSUSE 11 offers the best KDE 4 experience out there and will continue to be our reference distribution for KDE testing.

linux.com: The openSUSE version of KDE 4 alone is worth the download [..] Including KDE 4 is not as big of a risk for openSUSE as it might be for other major distributions because of the conservative and intuitive way KDE 4 is set up. openSUSE has given me hope that I could actually like KDE 4.
