Nexus 7 not just for consumption?

I've read quite a few articles in which the Nexus 7 is referred to as a consumption-only device. Does anybody have any thoughts on whether a 7" tablet could be used effectively for productivity?

To put the question in greater context, I'm a writer and a lot of what I do is journalism-style reporting and interviewing. Seems to me like a 7" form factor would be great for typing notes (I've tried it with an iPad and it just feel clunky), recording audio, blog-posting, writing w/ Google Drive, etc.

Anybody out there use a 7" tablet in a similar fashion -- or for productivity in general -- and pleased with the experience?
