Techspot published a review of the Aten Laptop USB KVM Switch.
Quote from the review: "Aten has been in the business of producing KVM switches (short for Keyboard/Video/Mouse) for over twenty years. During this time, they have positioned themselves as the world’s largest KVM manufacturer offering enterprise solutions as well as products for everyday consumers. Today we will be taking a look at one of their newer consumer products, the Laptop USB KVM switch (model CS661), which allows the user to easily link two computers together using a single plug-and-play cable. Once linked, you can remotely control one system from the other as well as seamlessly transfer data between the two.
Whereas standard KVM switches let you control multiple PCs from a single keyboard, monitor and mouse, this "KVM switch" differs on the actual functionality and purpose of the device. In fact, rather than calling it a KVM switch, this USB device is more of a wired remote desktop solution."
