"Just launched on Kickstarter, the LeviSync iPad cradle arm for iMac is not the most elegant solution to have an iPad float next to your Mac’s display, but its industrial strength aluminium and steel design certainly looks made to last. The LeviSync’s arm swings to position on either side of your of your iMac, builds in a four-port USB hub, and is compatible with every generation of iPad and iMacs starting from the late 2007 model. It also works in landscape or portrait mode and makes it easy to hook up to your iMac’s audio output source. Another great feature is the stand. It requires no screws or additional parts for installation and simply slides onto your iMac’s existing stand. This is perhaps most useful for those taking advantage of solutions such as AirDisplay for using iPad as a second monitor. You will have to pledge at least $199 to get your hands on the LeviSync when it lands in production, but it will eventually retail for $249. The inventors will first have to reach their $60,000 funding goal…" - Me from Bookmarklet

Hmm... kinda pricey considering the Hoverbar's $80. http://bit.ly/KJVGjq - ronin
