Logitech K780 Review: Is This the Best Multi-Device Keyboard for Everyday Work?
Quick Answer: Is the Logitech K780 Worth It?
Yes, especially if you regularly type on a computer, tablet, and phone from one desk. Its dedicated Easy-Switch keys and built-in cradle create a cleaner multi-device workflow than a conventional office keyboard. The tradeoffs are its large footprint, lack of backlighting, and round keys that may require a short adjustment period.
1. Design and Device Cradle
The K780's defining feature is the long cradle above the keys. It can keep compatible mobile devices upright while you type, avoiding a separate tablet stand. The graphite body and circular keys give it a distinctive look, while the number pad makes it practical for spreadsheets and regular office work.
The cradle adds real utility, but the K780 is wide and better suited to a permanent desk than a travel bag.
2. Typing Experience
The rounded, low-profile keys are designed for quiet everyday typing. They feel different from square laptop keys and mechanical switches, so accuracy may improve after a brief learning period. The layout includes familiar shortcuts and a full number pad, making the K780 more useful for productivity than compact tablet keyboards.
The low-profile design suits libraries, shared offices, and home workspaces where loud mechanical switches would be distracting.
3. Switching Between Three Devices
Three white Easy-Switch keys let the keyboard move among paired devices. A typical setup might connect a desktop or laptop, a tablet, and a phone. The benefit is not raw typing speed; it is continuity—replying to a message on a phone and returning to a document without changing keyboards.
The K780 is most compelling when the cradle and Easy-Switch buttons are used together rather than as a basic single-computer keyboard.
4. Key Features at a Glance
Three Easy-Switch Keys
Move among up to three paired compatible devices.
Integrated Cradle
Holds compatible phones and tablets at a readable angle, including devices up to a 12-inch iPad according to Logitech.
Full-Size Layout
Includes a number pad for spreadsheets and data entry while using a relatively compact frame.
Long Battery Claim
Logitech advertises up to 24 months from two AAA batteries, depending on use.
5. Connectivity, Compatibility, and Setup
The K780 connects through Bluetooth or Logitech's Unifying USB receiver. That distinction matters: the older Unifying receiver and newer Logi Bolt receiver are separate systems, so buyers should not assume that a Bolt dongle will pair with the K780.
Logitech lists support for Windows, macOS, ChromeOS, Android, iOS, and iPadOS. The keyboard adapts common shortcuts to the selected operating system, which is useful when moving from a Windows computer to an iPad or Mac.
