I am currently using the Logitech K760 keyboard with
1) ipad
2) Mac Mini
3) iphone
Quick bluetooth switching between the 3 devices with a single button press.
Powered by the sunlight, ceiling light or monitor glare. No batteries needed.
The downside? As far as I know, you can only get it from
Amazon.com
But it is quite reasonably priced, especially with Amazon global free shipping
