There’s isn’t much special about a 9 inch monitor, unless it’s the touchscreen kind, and it can connect to both PCs and Macs by way of USB port, giving you a second monitor without the usual hassles involved.
The iMO eye9 from Mino Monitors has a 1024×600 resolution, uses resistive touchscreen technology, can be detached from its stand to be used as a viewing tablet, and while on the stand, it can be kept in landscape or portrait mode. It has a 1.3 megapixel webcam that can somehow be rotated 360 degrees, in case you really like walking around while you chat. A kickstand that usually counts as support for tablets, does double duty here as a stylus.
It weighs just 1.5 pounds, which lets a Flex-Arm Mount attach it to most any surface. The Flex-Arm sells separately and costs $40, while the iMO eye9 will sell for $230 starting November 20th.
