Lol, I've not seen that pic in forever.
But for real, even kids need sleep (actually more than adults due to still developing). Road trips for me when I was young was either: Cassette Walkman, listen to parents radio or look out the window. Sometimes having nothing got boring (especially driving through Texas), but I think it helped my imagination and self reflection time.
OnlyOffice is nice, but a tad controversial. It's UI is much much closer to how 365 looks.
