The game industry has been doing it for awhile - for example:

I don't see a mention of it on Wikipedia, but my understanding is that Nintendo had millions of parts stocked up for the Wii U, but the Wii U was such a commercial flop it didn't make sense to actually assemble those- they wouldn't have sold if Nintendo had built them.
So instead Nintendo built them into the simpler NES Classic.
IDK... does Nintendo have a bunch of those awful Wii U touchscreens laying around in storage somewhere? That had to have been one of the worst parts of the console. Apple had shown the world how to do touchscreens right with the iPhone in 2007, and for nobody knows why, Nintendo released a console with a touchscreen that felt like it belonged on a Palm from the 90s in 2012.
