Hi

"Some old time Fedora users may be aware of Fedora's poor track record
when it comes to KDE although things have been changing ever since the
release of KDE 4.x. I regularly try Fedora KDE and so far haven't been
fully convinced with the experience until now.
As a fan of both Fedora and KDE it gives me pleasure to say Fedora 15
with KDE 4.6.x is a great experience!"
