Nintendo Confirms Issue with Console
Nintendo confirmed that the Switch has a major issue. You can't transfer your saved games between systems.
Now this may not seem like a big deal, but imagine that at some point you break your system and need to get a new one, all that saved game data is gone. Not great news for people who are spending 40+ hours playing games like Zelda.
Also, if that is the case, what is the extra SD card slot even there for? To store games yes, but it would be a simple fix to allow the system to use this part as well.
In the statement they did mention "At this time..." so that could mean that they are working on a fix or planning to add that feature later.
