Addlogix's new UniXpress USB 2.0 Port Replicator is a good example that takes advantage of a single USB 2.0 connection to provide SVGA video, Ethernet, audio, mic-in, 5-port USB hub and also KVM support for 2 PCs. The video mode allows you to do mirroring, extending and replicating the display at up to 1280 x 1024 in 16-bit colors. Addlogix claims DVD playback is possible.

The KVM support is particularly useful if there's already a desktop with USB keyboards and mouse that you want to share with the notebook. The UniXpress has a hotkey that switches all peripherals between two PCs.

The price of having a future-proof solution is $199.99. [Contributed by EverythingUSB]
