Raspberry Pi 400 is your complete personal computer, built into a compact keyboard. Featuring a quad-core 64-bit processor, 4GB of RAM, wireless networking, dual-display output, and 4K video playback, as well as a 40-pin GPIO header, it's the most powerful and easy-to-use Raspberry Pi computer yet.
Throwback reference to the old Commodore 64 and Apple II with the computer and keyboard being integrated.
Mine arrived on Friday. I have managed to update it and that was about it this weekend.
