Bad timing to change the development focus of Kano OS to the x86 architecture + Windows 10, over ARM. I would not ever consider buying one of the new Kanos, because it is built for Windows, and I don’t want to support Windows.
I just bought my daughter a used Lenovo x230t and put LInux on it, because she out grew the Kano. I’m still planning on passing the Kano kit on to the younger child, but am a little disappointed in not being able to upgrade it properly. The Raspberry Pi 4 (plus cooling) would have been perfect for the Kano.
