It has been a long development cycle, with a lot of very hard work by the developers. In my opinion, the developers hard work has really paid off, this is an excellent release. It is available in KDE and Gnome3 LiveCD/USB images, and a (very large) DVD installer image, in 32-bit (i686) and 64-bit (x86_64) versions. If you want something other than a KDE or Gnome desktop, you can install from the DVD distribution, and get the latest Xfce or LXDE desktop. I have installed the KDE version on my laptop at home, and on several netbooks, and the Gnome version on another netbook, and it all went very smoothly.
The first thing to say about installation is that I don't think openSuSE gets enough credit for the speed and quality of their installer. It is nicely designed, it doesn't natter at you about a lot of unnecessary information, and when it gets down to the actual work of doing the installation, it is amazingly fast. I would estimate it at about 5 minutes to walk through the installer and answer the questions (considerably less for experienced users), 5-10 minutes to actually copy the live system to disk and boot it, and 5 minutes for the first boot and configuration of the installed system. Add a bit to that for the download of the ISO image (depends on the speed of your Internet connection, probably something between 2 and 5 minutes), and a few minutes to either burn a CD or copy to USB stick, and you can realistically expect to spend about 30 minutes getting openSuSE installed and running. That's pretty impressive.
The standard KDE 4.7 desktop is pretty familiar by now. Here it is, with the application menu open:
