You can use an iPhone or Android smartphone to control Sony's new HomeShare gadget, but the company also introduced this touch-screen Wi-Fi universal remote. It's also capable of controlling components via infrared signals, in addition to controlling HomeShare products via Wi-Fi. It's pricey at $300.
The NAS-SV10i is a HomeShare-compatible iPod dock, design to be connected to a separate home audio system, such as an AV receiver. Using HomeShare, you can wirelessly stream audio from any app on your phone, or music stored on your phone, from the NAS-SV10i to another HomeShare device. It comes out in March for $230.
