Molding all those parts for a single device dock is very expensive and you need enough volume to justify, more than what the Arrive could provide. Plus, WP is not optimized for landscape; Start screen, Zune, etc. So unless its an alarm clock, useless. If all charging ports were bottom center, a manufacturer could make a generic dock and provide inserts to align each specific WP model to the dock. And it they were assured, like with Apple, that the port and location would not change over multiple device generations they would be willing to put a good amout of cash into development. Then you would have docks that rivaled iPhones/iPod offerings, baring any port limitations. But as soon as the Arrive fades from our memories so would the whole custom design for that dock. A manufacturer would need to charge $99.99 just to break even.
