Logitech introduced an innovative multi-device Bluetooth keyboard, the Multi-Device K480, back in 2014. The K480 could be configured for use with up to three different devices, and definitely stood out in the crowded I/O peripherals market. Our wish-list for a follow-up product included an integrated trackball or touchpad and ability to use such multi-device peripherals with a wider range of PCs (not just the ones with Bluetooth capabilities).
