After days of releasing KDE4.1, the 1-click nothing but problems with dependency issues and are now seem to be fixed. The 1-click installer for KDE4.1 works perfectly OK with openSUSE 11.0.

Click Next on the KDE4.1 installation welcome window.
Click Next on the summary window which informs of the repository that will be downloaded and the software that will be downloaded and installed. This will start downloading the relevant dependencies and the packages itself ann install them on your openSUSE 11.0. YaST will add the Factory repository for KDE. This is just fine as it is a part of the openSUSE 11.1 build. All the new download CDs and DVDs are now updated with the KDE4.1 desktop environment package.
Once the installation is successful, click Finish in the installation summary window. Restart your computer or simply logoff and login from your Desktop for the KDE4.1 desktop to take effct and you can straight away see the changes on the desktop icons and more.

You might want to add info on adding the Extra Apps repository for KDE 4.1 as well, and let users know that it will be better to remove the Extra Apps repo for 4.0 if they add the Factory repo. The Extra Apps repo provides a lot of other apps.
