StarTech USB-to-VGA Docking Station
StarTech has a brand new USB-to-VGA 4-in-1 Docking Station that was specially devised to make it a snap when one wants to add multiple ports to a desktop or notebook system using a solitary USB 2.0 port. This makes it lean more towards a port replicator instead of a docking station, and comes wtih the following specifications :-

* VGA port
* Four USB ports
* One USB Mini B port
* One 10/100 Ethernet port
* Two 3.5 mm audio (mic, line out) ports

You can pick up this accessory for $129.99. Nothing essential, but definitely nice to own.
