Schools went with the Chromebook because they are extremely cheap. I think the state may have a case about software support, but it is really a muted point because the hardware warranty isn’t likely to outlast the software upgrade policy. I am not sure how Google and the OEMs only have to support the machines for 4 years. Most devices are 7 years and maybe longer in California..
My kids finished K-12 before K-12 put computers in the classroom. They had them at home from birth. They were well prepared to use computers in college and even that was primitive compared to what we had at the house.
Current schools have pretty good computer infrastructure and networking. Robotics clubs are common. As I prepare to retire from a very good career in computer hardware/software, I'll probably direct some time to work with the computer/robotics programs at the local schools/college.
