Okay, first of all calling people that use Chromebooks “slow” is maybe a little too far, maybe rein that in a little.
I can tell you from years of experience that using a Windows device isn’t a qualifier for being tech literate at all; the large majority of people don’t make any effort to learn how to use their device effectively, regardless of which OS it’s running.
In my organisation we’d tried giving Chromebooks to users with basic needs but very often they’d return it saying “it’s not good enough”. We’d check the usage reports and so many of them had apparently come to this decision within 30 minutes. We’d give them a Windows device instead and they’d still raise support tickets for basic, Google-able things like setting default apps and how to unmute their sound.
I have this theory that some people are ‘computer people’, in the same way some are dog people or cat people. Everyone else just doesn’t know how to have a ‘relationship’ with a computer and they get frustrated when they can’t immediately understand it.
Someone had mentioned AC may be fixed by the .NET4 fix in the last update - https://feddit.uk/comment/6293633
