What do you think causes people to hold on?

If it isn’t on fire yet don’t fix it, probably. I’ve heard of people still using Vista, which is certainly a choice.

Windows 10 is free

It’s not free legally in Australia, the US and I’m guessing the EU (I think Portugal is a. exception here). The rest I have no idea. The legal free upgrade from Windows 7 and 8/8.1 ended some time ago even though Microsoft will still accept those keys. That said, if you’re willing to deal with the activation watermark you don’t even need to crack Windows to make it work without a licence. 😉

Linux is a great idea for tech savvy users.

I was never able to get past the “I need a Windows partition stage” because there would always be obe game that I couldn’t play. It’s making great strides though and is one hell of a rabbit hole to jump down!
