I mean, I've had an Atari 65XE myself when I was a kid, but tvs are much bigger nowadays, less accessible and HDMI cables are much more difficult to run through the room (stiffness and length limits are real issues); OTOH keyboards and mice are easy to come by. The hard part of the Pi is the display. The kit also doesn't include a cam nor a headset, nor even a mic. This is super important for online learning. Maybe you could fit in a mic in the keyboard somewhere?
A Pi all-in-one (iPi if you excuse me) or a Pi-book in an affordable price range would be revolutionary. I have an old VGA-only monitor but guess what - no D-SUB on the Pi 400 and a proper dongle would be another... $30?
As is, nostalgia value is super-high but I don't feel it's as practical as one would hope without any kind of display.
