I prefer XFCE for lightweight uses (e.g. VM or raspberry Pi) and KDE for normal desktop use.
For me MATE isn’t quite light enough for lightweight when XFCE is there, and no where near attractive or pleasant enough for day-to-day use when RAM/CPU use isn’t a bottleneck. KDE is certainly more resource intense but up to 1gb of RAM and 1-3% CPU idle for a full featured, slick desktop environment is worth it.
I don’t really see the appeal of MATE unless you strongly want a GNOME 2 desktop. In which case, yes it makes sense. Although ironically you can make a very close but modern take on GNOME 2 with KDE with modern bells and whistles if you’re willing to customise KDE - it’s that flexible.
So who benefits from $30bn in spending on Laptops and Tablets? Oh Apple and Microsoft. Not students. Surprise surprise.
As with many of these articles there is a big caveat - Gen Z in the USA. It does not follow that this research applies across the world. It’d be interesting to see how other rich countries outcomes are different with their differing approaches to this. For example here in the UK I don’t believe there has been a wholesale move to laptops/tablets for every student in schools. Technology is certainly used but it’s not solely about students using laptops and tablets. Its things like smart wide boards, and the use of digital content to engage attention and so forth. Spending billions on laptops for all would be a scandal when school buildings need renewing for example.
I would hazard to suggest that the US education system is being corrupted in a similar way to other parts of the US state, with big expensive projects decided at state level by the Republicans and Democrats thanks to lobbying, benefiting big companies but not citizens. This is instead of money going to areas of proven benefit such as more teachers, school infrastructure renewal, or funding of homework clubs, after school activities, breakfast clubs or free school meals. Things proven to make a difference across the world but things that don’t benefit big US corporations.
And lets be honest, if you wanted to give every student a laptop you wouldn’t be going to Apple or Microsoft. You’d save money and go for generic hardware and a license free operating system like Linux. But that would be an anathema to both the Democrats and the Republicans, who have signed off huge spending on overpriced tech.
