I enjoyed the first episode.
It didn't cross that line between being a winsome indulgence and a grating, predictable, intelligence-insulting experience like Infinite Stratos did.... and is. The main character is likeable and, while unremarkable perhaps, avoids the pitfalls of the protagonists in similar works. The story apparently gets more weight later on when they start dealing more thoughtfully with the social and cultural issues underlying the world.
Considering it's an anime at least partly about moe and otaku culture, I was expecting a lot worse.
