With the last update, they say your save data automatically downloads to your Switch. That's one of the reasons why I loved Xbox and bought so many of them. With that option, and some of your suggestions, yes--I would buy a home only version of the Switch. It would need external HDD support. Then I'd just pick and choose which games I take on the go while the rest are stored on my home Switch. In fact, I love the idea, especially if it upped performance!
