USB Fever has released the WaterWear for the iPhone and iPod, and the Custom-Made Card Windshield Mount for the iPad. The former (pictured) is an US$26.99 case that’s water resistant (which is, you should note, not the same as waterproof).
The WaterWear (http://www.usbfever.com/index_eproduct_view.php?products_id=1992) is made of durable transparent material designed to prevent the intrusion of dust and water inside the special double chuck. The product comes with waterproof earphones.
The $25.99 Custom-Made Car Windshield Mount for iPad (http://www.usbfever.com/index_eproduct_view.php?products_id=1991) lets you attach the Apple table to a windshield. You can bend the bracket arm at any angle you wish. The mount is removable with a one-release button.
