Quick update: in the meantime Lenovo also added the IAL 255H variant to their own shop. And the great thing about that is: they also added the large battery, which ist not available at any of the German resellers (yet). A bit less than 1.1k€ for the 255H, 32 GB, 1 TB, 60 Wh battery, the IR camera and 1 year premium repair is a fair deal, so I ordered it.

The notebook looks really good considering the rather low price around 1k€ in Germany in the top configuration with 255H, 32 GB and 1 TB. Does anyone already have the notebook and can report any drawbacks besides the 45% NTSC screen and that it's only available with the small 45 Wh battery in Germany?
Also in case someone has the chance to post a picture of the German QWERTZ-keyboard layout that would be great.
@Mods: it would also be great to see a full review of that device on Notebookcheck.
