We expect the new mouse and keyboard from Apple by the end of the year
Apple never had the habit of updating its periphery too often. Current mouse and keyboard have become the standard for Mac users, because we have not seen new models since 2009.
In the archives of the FCC appeared sketches of the new generations Magic Mouse and Wireless Keyboard. Apparently they do not differ significantly from its predecessors, but we can expect changes in the hardware. The main one is that the new models will rely on Bluetooth 4.2 instead of Bluetooth 2.0, which will make the link with the new Mac models and iOS devices more energy efficient. Gone are also the slots for standard AA batteries, which will be replaced by integrated rechargeable lithium-ion modules. It is not yet certain, but we can expect fast switching between multiple devices, as we have seen in some keyboards Logitech, for example.
