You compare reinstalling Windows to rewiring the house, and then note that your wife did the former. How is she at rebuilding auto engines?
My point here is that people make a big deal out of the process of installing Linux. Fine, you can have somebody else do it. If your Windows PC gets bogged down with malware, you may very well have to have somebody reinstall Windows too. Happens all the time. What's the functional difference? What makes Linux harder for the user? Unless you just have to have your malware.
As far as the GUI being different, so is a Mac's. You can code assembly and and still stumble around on a Mac's GUI. That doesn't make a Mac super elite user hostile. It's a matter of what you grew up with (ha ha). And you don't have to be tech wizard to switch between a Mac and Windows -- I realize it helps to be younger.
