There's an ever increasing trend that for many the laptop has become the new desktop. Whether that's because of the affordability of low-end notebooks and popularity of netbooks, or because the more costly laptops can nearly replace a desktop in pure performance terms, many users are no longer relying on a desktop system for their computing needs.
The major advantage this poses is portability, being able to take your computer with you and use it anywhere, though once you are settled in at home or your office this same factor can play against you. Anyone who has used a notebook for an extended period of time knows that a small screen, cramped keyboard and touch pad can be frustrating and really slow you down. To remedy home/office situations like this, StarTech has developed the USB 4-in-1 Docking Station with VGA, a KVM-like device that allows you to connect commonly used peripherals and an external monitor all through a single USB cable.
Besides simplifying multiple USB connections which you could manage using a simple hub, the docking station can also pass-through your audio and even video output using a single USB port for painless operation.
