Logitech Harmony Link compare

Logitech's Harmony Link lets you use your iPad, iPhone, or Android phone as a remote control, but touch-screen limitations and the iPad app's limited TV listings mean you're better off with a standard Harmony remote.

Setting up the Logitech Harmony Adapter for PlayStation 3 isn't completely painless (or cheap), but once up and running, it does provide total control over your PS3 including the ability to power it on and off.

For cars with an auxiliary input but no native Bluetooth, the GoGroove SmartMini Aux is an effective means of adding both hands-free call capability and audio streaming from a smartphone.

If you're looking for a relatively cheap way to add Bluetooth wireless audio streaming to a powered speaker or audio component with an audio input, the Logitech Wireless Speaker Adapter is a good solution.
