You read the title right, it’s now available for purchase. Might I add I am about to order mines now. This dock is available for purchase directly from Google just like the Nexus One was and still is.

When ordering the dock there isn’t a picture of it for you to see, that is on the tech specs page for the Nexus One and I posted the picture here. Here’s the description of the Dock taken directly from the Google tech spec page.
“The Nexus One Desktop Dock is an elegant place to charge your phone, on your desk or nightstand.
Just drop your phone in the Desktop Dock, and the Clock app launches automatically, making it easy to:
• Check the local time and weather
• Set and clear alarms
• Watch a slideshow of your photos
• Play music
• Dim your phone’s display for nighttime use
We also include a 3.5mm-to-RCA audio cable that allows you to connect the dock to your stereo, so you can listen to your phone’s music on your stereo system.”
