Well I agree with you regarding KDE4, I've been trying it out via teh openSUSE KDE4 live CDs, and yes it needs sometime before its ready for primetime. Fedora 9 will be the first fedora I'l be taking a deeplook at, last time I tried was FC6, and I was left with a rather bad taste.
And yup. I'm a SuSE user since 6.3, and a huge openSUSE fan, openSUSE 10.3 is what powers my Dell.
