Great Nexus 7 apps

Hi guys,

I just got my Nexus 7 a few days ago but have been struggling to find great apps that are optimized for the 7" display. While most apps work quite well even without optimization some could use that extra space. I also just moved to Spain so Google Play is a bit cluttered with either stuff that I don't understand or that I'm simply not interested in.

So I'm wondering what are your favorite N7 apps?
