Logitech K480 – Bluetooth Multi-Device Keyboard
I've been using the K810 [1] for some time for all my computers. I find it absolutely brilliant to type on (being mostly in vim, the awkward home/end, page up/down, arrows etc don't matter very much), and it also has the ability to switch between 3 paired bluetooth devices.
There is also the Lenovo Thinkpad Compact Bluetooth [2], which I haven't tried, but allegedly "features a simplified pairing with the system through Near Field Communication (NFC) tag. Simply tap and pair with an NFC-enabled system." It also has a TrackPoint nipple.
Of course, neither of these have the slot for phones/tablets.[1] http://www.logitech.com/en-us/product/bluetooth-illuminated-...
