I am a big fan of Twelve South products and particularly have my eye on the HoverBar Duo. One thing I don’t like is that it clamps the iPad instead of using the magnets (or potentially the connector pins). Do these exist?

HoverBar Duo is a flexible arm that includes a desktop base and adjustable shelf clamp. Use it like a multi-tool to get serious creative work done on an iPad.
