The iOstand ($100) is a minimally designed mount made out of solid steel with either a stainless steel or powdercoat finish. You use it by attaching an iOadapt adapter (a small disc less than 1mm thick) to the back of your device or its case. The disc -- and your device -- then magnetically snaps into place on the iOcore, the carrier on top of the mount. You can rotate your tablet in almost any direction.
The iOstand comes with two iOadapts so that you can use it with more than one device. There are also other stands, like the iOwall wall mount ($60) or the smaller iOmini ($90), which is made specifically for use with smartphones.
