Fujitsu has launched three new models of keyboards, and its ultra compact keyboard layout can be traced back to the classic "happy hacking" keyboard in the 1990s.While the keyboard layout remains unchanged, the new model launched on CES today has been modernized in several key areas. All three keyboards now have a usb-c interface, and two of them can also be connected via Bluetooth and support software to remap their keys.

The release is significant because Fujitsu rarely updates its HHKB lineup. The last new keyboard in the series is the first Bluetooth model since 2016, according to Wikipedia. Until then, the series has remained unchanged since 2011.

Fujitsu said all three keyboards use electrostatic capacitive key switches, while the Type-S keyboard has an extra "buffer" inside to make the keyboard tap quieter. The new keyboards are available in white or gray, and they are not cheap. The non-bluetooth Pro3 Classic is the cheapest of the three, for $217, compared with $264 for the Pro3 Hybrid and $320 for the Pro3 Hybrid Type-S. The HHKB Pro3 series is sold through Fujitsu's online stores as well as other retailers such as Amazon.
