There are two major reasons I can think of to hack a game console. The first one is obvious: so you can play cracked copies of games. That’s why modern consoles are so difficult to hack, because millions of dollars are on the line. But some people just want to run any software they choose on the hardware they own. And for those people, Linux on the Switch is a huge achievement.
This hack boasts touchscreen support, a fully operational
death star web browser, and a GPU-powered demo app. Sadly, there are no details out on how you can do it yourself, but Twitter user fail0verlow has a nice video of it in action embedded in a tweet.
