iPad dock is available at Best Buy. Plenty of them.

The iPad keyboard dock is not available yet. At least not at any of the Best Buy stores I've been to around Baltimore.
 
Got dock

I pre-ordered the keyboard dock and was quoted "end of April" but it showed up this past Monday.

It works well with special keys for the iPad. It has a pass through connector so you can still have it plugged into a power source or plug in one of those special devices like the memory card reader. Unlike the wireless Bluetooth keyboard, it does not tie up that channel so you can use your headphones or other BT device the same time as you use the keyboard.

Now the bad news. It only lets you use the iPad in Portrait mode. It weights 1.5lbs. It's too thick to put in a thin briefcase or messenger bag.

I like the lightness (11oz) and versatility of the wireless keyboard. It has no special keys for the iPad but you don't really need them.
