The Raspberry Pi 400 is a complete Raspberry Pi 4-based personal computer, integrated into a keyboard. By incorporating the board into a keyboard, it removes the need for a case and other accessories normally needed to run a Raspberry and creates a more clean configuration. It makes for the perfect configuration for a public machine or in an educational setting including the incorporation of a Kensington lock (Locking port used on laptops for security in public spaces).
The Raspberry Pi 400 features a Broadcom 1.8GHz quad-core ARM Cortex-A72 CPU with 4GB of DDR4 RAM. VideoCore VI graphics (OpenGL ES 3.1, Vulkan) and 4kp60 HEVC decode provide the ability to run a 4k monitor at 60FPS or 2x 4k monitors at 30FPS through the two micro HDMI ports. An Ethernet port provides true Gigabit Ethernet support and there's two USB 3.0 and 1 USB 2.0 ports available for accessories and HIDs. A USB-C port is used for power and supports 5V, 3A operation. Finally the standard Raspberry Pi 40 pin connector is present on the back of the keyboard for HAT support.
The Kit includes everything else you will need to get started using the Raspberry Pi 400. It includes a USB Type C power adapter (North American), a wired mouse, 1 meter micro HDMI to HDMI cable (monitor not included), a 16GB micro SD with Raspbian pre-loaded, and the Raspberry Pi Beginners Guide book.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

A convenient all-in-one computer that is super easy to set up. A great tool to let kids play with and tinker.
A few nit-picks. Wish they had full sized HDMI ports (a cable does come with the unit though). Wish they had a USB port on the other side of the keyboard to plug the mouse into. Considering most are right handed, having the USB ports on the left shortens the mouse cable quite a bit.
I was impressed by the performance of this device for basic computing tasks. I had tried to use Raspberry PIs for general purpose computing in the past. This is the first time I felt it was fast enough for that type of work.
Highly recommended for those looking to get started with Raspberry Pi. Highly recommended for those with kids that want to start learning how to code or tinker. I also appreciate the nostalgia this brings as it really reminds me of those early 80s all in one computers.
