I think its more of a concern of the machine's age. Its not going to run forever. Windows has changed so much that to many its unrecognizable. Why not look for something open source and that grams may like?
That is a very good point. I set up a new computer for my sister with Windows 7. Even that was enough to give her some issues. W8? Truly unrecognizeable. fuggidaboutit!
But her old computer was about to crap out, and it was A Windows XP Pro system that was - beyond all belief - not one update. It used a lot of programs that aren't in existance any more, and/or not compatible with W7. No compatibility mode, nothing - they wouldn't even install.
This is an extreme example of what people are up against. But still an example.
So I just sat down with her and explained that we'd get close to what she had, but 14 years is a log time in computer terms, so she'd have to learn a little bit.
Path of least resistance type stuff. Windows 7 allowed for it. W8? Not hardly.
To the topic at hand, installing W8 is not really a good option for a lot of people, especially if they don't have a touchscreen. Yeah, we can do this and that, and do something to make it looks sorta like kinda something. But it's such a huge step, and not even a step forward. It's learning almost everything new to do the same thing you were doing before. And some things end up arbittrarily different, like on my Wife's W8 Laptop, the integral mail program won't do POPMail. or only certain programs can be turned into desktop shortcuts.
And since whenever you set up or fix a computer for a friend or relative, you own every problem that happens afterward, I simply won't install or work on a W8 computer aside from my wife's touchscreen laptop. Linux or W7 is the only thing I'll support.
And I heartily recommend Mint.
