Best iPad/tablet mounts?
 

I'm looking for a long swingarm style iPad/tablet mount that could attach to a wall. Most of the ones that I have found are more desktop or vehicle oriented. I'm thinking of a swingarm style similar to the kinds that are available for monitors and TVs.

Something like this, but for a tablet: http://www.projectorsuperstore.com/s...FWwQ7AodnBAA5Q

Any ideas?
