Yeah and recently got an argument with someone saying that the SD was no competitor for the Switch.
In my opinion both are directly trying to fill a market where you can play games anywhere.
It’s true that Nintendo also has their own closed games that can only be played on their hardware (officially at least).
But beyond each console’s game library the need for having a portable console is a more important factor.
I remember I started using more Skype after it MSN Messenger.
But I’d say it got killed by WhatsApp on mobile phones.
