While iPad stands often feel like a dime-a-dozen commodity accessory after a decade of Apple tablets, we seem to be in the midst of a sudden renaissance for this product category. You have Kensington’s new StudioDock, which is impressive in both its size and feature set and comes with a price tag to match. Then there’s the Satechi Aluminum Desktop Stand that I wrote about Sunday and back in January. Now we come to a third high quality stand released this year that brings both great construction and a high level of versatility. This stand is the HoverBar Duo from Twelve South.
