A bunch of amazing people who refer to themselves as the switchroot group have been working hard on getting alternative platforms running on exploitable Nintendo Switch units, including Ubuntu, forks of LineageOS, originating from the Nvidia Shield TV branches of Android. Running LineageOS on Nintendo's amazingly popular handheld/home console is actually nothing new.
Put the two together, sprinkle-in a hefty dose of tinkering and you get a janky 'fusion' recipe that is just hard to pass by.
Less surprising still is the fact that we love Android. It will hardly come as a surprise that us geek folk over at GSMArena love the Nintendo Switch.
