The EasiDock, marketed through Mobility Electronics, is a universal port replicator that connects through your laptop's USB port. The EasiDock provides a 10baseT Ethernet NIC, readers for both CompactFlash and SmartMedia cards, a spare RS-232 serial port and parallel port, and four additional USB ports. It works with any laptop, and is quite a bit cheaper than OEM port replicators.

Instead of spending big bucks on an OEM unit, you can get a few of these and have one for portable use and the others set up where you work, since everything will be connected to it (like Ethernet and printers) and all you'll need to do is connect one USB cable to activate it.
