gDocs is probably a big influence as well... as an all around value, I really like the Chromebooks... from a security standpoint, I tend to like them for mom & granda even more... (with uBlock)
There's something to be said for a device where you can just grab a new one off of the laptop cart, install nothing, and login as any user with the full experience available.
Windows domain-connected PCs kinda accomplish that, but with a lot more management overhead.
That might have been interesting if Mozilla had been able to get it to run on Macs.
We have a spare/guest Chromebook and it's been nice to hand it to one of my two daughters when they've cracked the screen. I'm not in IT but I'm just imagining how much easier Chromebooks would make my life. Especially if the management software is even halfway-good.
I'm sure that Microsoft Word can be set to automatically save but somebody probably has to do that. And the school might have disabled it because the kids are sharing the MacBooks and still using thumb drives.
If Bobby or Betty just lets it save, now you have to find the laptop the doc was automatically saved to.
Or maybe it was saved to the machine instead of her thumb drive and the IT guy just told her she lost it.
I try to do tech support for my kids and parents hands-on because details that don't matter to them do matter to the OS or apps.
