Sometimes crazy licensing schemes from companies create some truly mindnumbing absurdities. Take the Nintendo Switch. If you download a free app or game from the store, it installs it as a virtual card. If you want to play that same app on a different switch and you don't have the other one with you? Normally, since it's free it would make sense to just redownload it, but no, Nintendo makes it a virtual card that can only be installed on one of your systems at a time.
