The CrowPi2 transforms the Raspberry Pi into a compact laptop with a removable wireless keyboard and trackpad. The device, which has an 11.6-inch and 1080p IPS display, is compatible with multiple operating systems and the STEAM Education platform.

I honestly can't help but feel like these sort of projects that "turn the raspberry pi into a desktop/laptop" are largely pointless.
It reminds me when, years ago, many schools introduced dozens of raspberry pi's to their ICT suites as desktop computers to teach kids programming, only to find they were slower, less intuitive than the Windows desktops they already had and most of the software would run on Windows anyway.
Whilst the latest iteration of the Pi may now marginally have the capability to act as a full desktop, that isn't where its greatest value proposition lies.
The Pi's real strengths lie primarily in the capabilities it offers for makers, through its large collection of interfaces and then secondarily as a low powered, headless Linux computer.
