The installer is the usual Ubuntu one. You can install from the boot screen or the live session. It's easy to use and supports encryption of /home. It offers to download media codecs and updates; it doesn't offer to download language packs, but it does it anyway! The installation took an hour, of which three-quarters was spent downloading.

The installed software is all KDE, except LibreOffice. (There's no Calligra, despite the statement above). LibreOffice (apart from missing Java) seems to be the only reliable thing there. Whatever I ran from the CLI left a warning: “may misbehave, could lead to crashes, should not happen, socket error, broken resource”. They ran, but for how long? The web-browser Rekonq (does anyone actually want that?) didn't even run: “illegal instruction”.

There are much better KDE distros than this: Mepis or OpenSUSE, for a start.
