I have been waiting to try the Logitech K780 Multi-Device Wireless Keyboard. You see, it is very similar to last year's K480, which I own.
I love my K480 even though it is not the prettiest keyboard, with its bulky and squarish shape. It also lacks a numeric keypad and has quite a big footprint.
But the K480 can link wirelessly via Bluetooth to three devices of different platforms at the same time. You can switch to each device by turning an Easy-Switch dial. It even has a groove to hold your smartphone and tablet.
The K780 ups the ante by having Bluetooth, as well as by being able to connect to computers without Bluetooth via an included Logitech Unifying USB wireless adapter. This adapter is stored in the rear battery compartment of the keyboard.
The K780 can connect up to three devices using both Bluetooth and the USB adapter at the same time. Great if you want to connect to an office desktop computer, as these usually do not have Bluetooth.
It is compatible with Windows, Mac, Android and iOS devices.
CONNECTIVITY: Bluetooth, Logitech Unifying protocol (2.4GHz)
VALUE FOR MONEY: 4/5
For most of this review, I had the keyboard connected to my 12.9- inch iPad Pro and Samsung Galaxy S7 edge via Bluetooth, as well as to my office Windows laptop via the USB adapter.
Compared with the K480, the K780 looks more like a normal keyboard with the addition of a numeric keypad. This keyboard has all the the function and shortcut keys that you would find in both Mac and Windows keyboards. I found myself typing away on the K780 with minimal mistakes.
Similar to the K480, the K780 has keys that are concave and rounded. The keys have good tactile response and are nicely spaced out. But the keys are fairly quiet, unlike mechanical keys.
There is a groove behind the keys to hold smartphones and tablets like the 12.9-inch iPad Pro.
I found that the iPad Pro can be placed in both landscape and portrait orientations. But it is less stable in portrait mode.
Instead of having the dial of the K480, there are now three Easy-Switch keys, where the F1 to F3 keys usually sit.
To pair using Bluetooth, just press one of the Easy-Switch keys for 3sec and wait for the keyboard to show up on the Bluetooth Settings menu of your device.
For pairing using the USB adapter, there is an additional step. After selecting the Easy-Switch key, you need to press the function and O keys for 3sec if you are using a Mac, or the function and P keys for 3sec if you are using a Windows computer.
Once pairing is done, switching among the devices is plain sailing. Just press the respective Easy- Switch key, and you can type away immediately.
The keyboard is powered by two AA batteries that are supposed to last for two years. So you might find yourself changing your smartphone before changing the keyboard's batteries.
On the downside, the K780 is much more expensive than the K480, which retails for $65. I also wish the keys have backlight.
•Verdict: For the modern office worker typing with different devices, the Logitech K780 is a must-have.
