According to the user manual:
Remember you can only link to one device at a time via Bluetooth, whether a keyboard or mouse. The other device must be connected via USB. You can also connect to a single Bluetooth device which contains both a mouse and keyboard.
This seems completely ridiculous, and is contrary to all the promotional images that show it with a Bluetooth keyboard and mouse. I would consider it seriously broken if this was true.
I currently only have a BT keyboard, and would still need to buy a mouse. Has anybody tried it with both keyboard and mouse connected through BT?
