Considering Google Classrooms is used by a significant percentage of public schools, I have no idea why you think Portugal is special here.
Also, given the frequency of families having issues with the Cuco MDM used to lock out the Windows computers they handed to kids during COVID, and what kids do which such computers, I'm doubly unsure it was a smart idea to offer shitty Windows laptops vs. shitty Chromebooks.
Schools around the world give kids Chromebooks (or iPads) because they're harder to fuck and easier to unfuck. Windows still sucks at this, and no one came up with a coherent — locked down — Linux platform to achieve the same.
I am Portuguese, have family ties with teachers still into the active, I guess.
That kind of stuff is mostly US school system, schools in countries that go with USA into G7 meetings, or wealthy enough for that kind of stuff maybe.
Not every country has the pleasure to enjoy a school system swimming in money to offer computers to kids, in every single school.
Not even during COVID was every Portuguese family granted the pleasure to have a device offered to them, some lucky ones did, a large majority only saw them on the news, and as usual the burden was on the family to come up with a solution to all their kids attending the various school levels.
And lets not even go to such great stuff like Magalhães, e-escola, and who got to profit from it.
