The powercore is a little puck that plugs into Powerplay-compatible wireless mice. (Did Logitech hire the Nvidia marketing guru who came up with 'Forceware' or something?) The Powerplay bundle ($100 in the US, probably £90 in the UK) consists of a wireless charging base, two mousing surfaces (soft and hard) that you can switch between, and a powercore module. Your wireless mouse will never again run out of battery. Logitech has found a legitimate use for wireless charging: the Powerplay mouse pad, which constantly charges your wireless mouse. Say a quick prayer to your favoured deity.
