OPENSuSE 10.3, x86_64.
I had some display issues. I also didn't like the default interface at all. It was too annoying to navigate! I wound up customizing it, but for starting out...man...it was a pain. The display issues were mostly related to Compiz-Fusion, which, for one reason or another, I couldn't get to work. So instead I was stuck with Xgl...which was nice, but it didn't have the customization that Compiz-Fusion offered. It also seemed a little sluggish (compared to Fedora 8, which I am now running). Overall, I just didn't like it. I didn't like the way if felt.
Don't let that deter you, though! Everyone's different.
