Logitech K480 Multi-Device Bluetooth Keyboard Capsule Review
 

We have been doing round-ups of various input devices fit for HTPC purposes. Some of the vendors have started shipping with Bluetooth instead of using a proprietary communication mechanism over 2.4 GHz RF. The advantage of Bluetooth is its versatility and presence in almost all modern mobile devices (smartphones and tablets). These don't support a full-size USB host port for plugging in the USB RF receiver dongles. Utilizing Bluetooth enables these input devices to communicate with the rising crop of mobile devices as well as interface with traditional PCs. Communication with PCs can be enabled by using either an inbuilt card - common in most notebooks which integrate Bluetooth and Wi-Fi capabilities in a single mPCIe card - or, an explicit Bluetooth dongle.
