I didn't know that things like this existed. I can have my computer and my phone on the desk in front of me and type on whichever one I need to at the press of a key. Awesome for typing text messages without picking up the phone and using the on-screen keyboard. Very happy.

Love this keyboard. It helps me to switch between multiple devices with single click and be always on top of them. Round keys feels a bit strange at the very beginning, but once you get used to them nothing else can stand. Keyboard is a little bit heavy, but it is designed that way to be able to hold tablet or phone. I like the idea of having both layouts available: Apple and standard PC for Alt/Meta/Control/Com­mand. Idea of two protocols: unifying receiver and Bluetooth is outstanding.

Easy to setup with multiple computers and the android phone. And just as easy to switch between the different devices.

Life it, only issue is if you have Bluetooth active on laptop it gets confused if you’re trying to connect with dongle. Had to disable Bluetooth to get it to work on the work laptop. Worked 1st time with iPad and iPhone ;)

Great for being able to type on a tablet, computer or phone. Even if you don't use it with a phone or tablet, it's nice having the cradle to hold your device in place to easily view it.

Back in the day if you wanted to share one keyboard and one mouse between two computers, you had to use a clunky switch box that was connected to both devices. Today Bluetooth makes wires and stand alone switch boxes obsolete.

2 AAA batteries power the keyboard for up to 24 months; Comfortable to type on; No weird key layout; Easy switching between 3 paired devices

None

In this day and age you are probably using anywhere from 2-4 devices on the daily. I can imagine one of those would at least be a PC and then a smartphone. Some might have multiple smartphones and even a tablet. Going from typing on your PC to your mobile device can definitely be a chore.

The Logitech K780 bluetooth keyboard pairs with a tablet, phone, and PC, at the same time, and can be easily switched between any of the three. Does this 3-in-1 keyboard[...]

Logitech certainly understands the keyboard game, and the K780 is a smooth unit to work with. Fingers don't need to press down too hard or far to register strokes (easy on fatigue), and the keys are able to handle 112+ wpm continual typing without any skips/misses, delays, or doubling-up.

Keyboards , especially non-gaming ones, can be a little boring and one dimensional at times. The K780 wireless one from Logitech, however, cannot be described as such. It's designed not simply to work in conjunction with one's PC, but also pairs with smartphones and tablets too.

Silent keystroke; Quick device pairing; Solidly built

Circular key design not for everyone
