Toshiba is really going for the comprehensive approach with their Wireless USB DynaDock. This device provides a docking solution for your laptop, but adds on functionality with a high performance video controller and much more.
The DynaDock is powered by an Aleron AL5000 chipset. It is also simple to use, with connection occurring just by being in the dock's range. You can use any Windows-based computer with this device so long as it has a USB 2.0 port. Three displays can be connected at once and its slim design make it so you save considerable space.
A wired USB connection is also possible. The DynaDock also supports Ethernet, a bi-directional isochronous data mode and more. Video input is included as well. We can't locate pricing information on this one, but we'll be sure to let you know when we do.
