The Hoverbar is an adjustable arm created by a company called TwelveSouth that connects your iPad 2 to your Mac. It features a sleek black, flexible arm that connects to your Mac using a sturdy, silicone-lined clamp that leaves no trace whatsoever while attached to your iPad 2. Once the iPad 2 is attached, the Hoverbar makes it appear as if its floating right next to your Mac.
You can also use the Hoverbar in other places by attaching it to a kitchen cabinet or even a table to set up a mini workstation with your iPad 2.
The Hoverbar adjustable arm is available for $79.99 with free shipping from here
