This is a really cool concept. I love the paper construction, and the versitility. Some pros and cons though.
Pros:
-small size will make shipping easy.
-can fit in most any space.
-ergonomic
-really cool
Cons:
-Ouch- price really high for what looks small and inexpensive. $700. each is steep.
-It's still in development and not available yet.
-Real user feedback yet to come.
I'll wait for the formal release and more widespread feedback.
