Raspberry Pi Foundation has announced the launch of the Pi 400 — a complete PC within a keyboard aimed at getting users up and running without much hassle. The Raspberry Pi 400 is much similar to the Pi 4 in terms of specs but comes with a slightly faster CPU. The Pi 400 is available as a standalone keyboard-PC for US$70 or as a PC desktop kit with all accessories for US$100.
