There's not much to say about a dock, is there? It's pretty simple: You put your iDevice on a dock and, depending on the functionality, you may charge, sync or blast some audio out. In the case of the Gravitas from Henge Docks, you can do all of those things plus there's some magic inside.
That magic is a special alloy, 265 percent more dense than aluminum, that gives the Gravitas an astounding amount of heft. As a result, you can dock your iDevices into the smallish Gravitas, but remove them without holding the dock with your other hand. It's a beautiful thing, because the dock looks aluminum, but just stays then when you lift your device up.
Besides weighing almost one kilogram, the Gravitas offers an audio line out, and a USB data / power connection. There are plastic inserts to accommodate iPads and iPhones. They'll have 30-pin and Lightning versions available at launch.
The Gravitas should be shipping in March for US$69. Henge is here at Macworld, and you can reserve yours with no obligation to buy when it is released. Henge makes some useful, nicely designed gear (stay tuned for another item we spotted at CES and at Macworld), so if you're in the market for a stylish and useful dock, check into the Gravitas.
