I was looking for a docking station for my Asus G73J Ubuntu laptop when I ran across the Plugable docking station. Normally, I would not have considered a USB-based docking station, but since this laptop does not come with an ExpressCard, I have little choice.
What initially caught my attention about this universal docking station was that, unlike most of the others, it supported Linux in addition to Mac and Windows. What sealed the deal for me though was seeing it attached to a Nexus One :)
