I like this guys channel but I have to admit some of his videos are extremely misleading I used Windows 7 as a daily driver on my old laptop for a while before installing Linux on it and I watched Youtube and used Discord just fine.
They shouldn't have announced this until completion. I bet Nintendo is already working to shut this down.. Like how Link Awakening port that was shut down within days.
Depends on your device, some manufacturers block the ability to do any of this. ex: Microsoft Surface Pro has locked down the firmware via Windows Update. (Can downgrade via Linux) Though I'm sure its doable with Windows, just requires a bit more...
Depends on the hardware and how you use your device/PC.
If you want to play games without the hassle of having to learn a new OS, then stick with Windows.
If you only use the device for web browsing, video streaming etc. (media purpose) Then...
If you decide to take the easy way out, at least do it some interesting way, like 5 fishing magnets and ropes... Run out to the space x rocket as it's about to take off.... Ohhhh add some snow skiis and skii into to space!!!
