Taking your IBM from the office to home or moving it from one room to another will no longer require disconnecting and reconnecting several devices.
The docking station replicates all of the connectors and ports from your laptop and routes the connectors to the back of the dock.

Provides workspace flexibility with convenient cable management and viewing expandability with additional display support. If you use your laptop in a work or home office environment the IBM X4 UltraBase Dock Station gives you a comfortable work space.

You can even add other peripherals such as a printer scanner iPod dock/cable and more!
By using it it can also gives you ease of mobility by not needing to unplug and re-plug multiple peripherals to access your printer or other devices.
