Here's someone using the (officially unused) NES expansion port to send a Tweet from the console: https://www.trapzz.com/?page_id=292

Thanks! this is the weird stuff I like to see.

Most of my time-wasters (games, forums, youtube) are better on the bigger screen, which helps keep it from leaving the house with me (and keeps my smartphone usage down, in turn). The apps are there, but I don't pull out the phone for much except texts, pictures, or when I'm stuck in a quiet waiting room.

It made sense to me, finances are a common reason someone has to input a lot of numbers.
