I didn't find it in the German market as well.
It's in the US market.
It's a huge letdown though.
Interface nothing special. Homescreen heavily loaded with tons on icons, not very nice.
AND: I only find 36 of my ca. 350 eBooks I've bought from Sony for download. I've downloaded way more (ca. 200) in ePUB format from their store.
Unfortunately, no reason for me to keep it.
I easily can download those ePUBs to other DRM-capable apps.
