Getting a smartphone in 2010 was what gave me the confidence to switch to Arch Linux, knowing I could always look things up on the wiki as necessary.
I also think my first computer that could boot from USB was the one I bought in 2011, too. Everything before that I had to physically burn a CD.
Not just to save cost. It's basically OS-agnostic from the user's point of view. The web app works fine in desktop Linux, MacOS, or Windows. In other words, when I'm on Linux I can have a solid user experience on apps that were designed by people who have never thought about Linux in their life.
Meanwhile, porting native programs between OSes often means someone's gotta maintain the libraries that call the right desktop/windowing APIs and behavior between each version of Windows, MacOS, and the windowing systems of Linux, not all of which always work in expected or consistent ways.
