Motorola offers it Motorola RZ100 Bluetooth Smart Controller for Android, model no. 89506N, for $9.99 plus $5 for shipping. That's the lowest total price we could find by $8, although we saw it for a buck less in June. It features a multi-touch trackpad and allows you to access apps and content on your docked smartphone or tablet; it's intended to be used when your device is connected to your TV, and it also allows you to take calls.
