Know that it might still be a while before Switch homebrew can do anything useful. Plus, you won't be able to play games that require firmware past 3.0.0 for a long time. And most things homebrew could do early on can probably be done much, much better by a smartphone or other device. Maybe you might wanna buy a Switch now while it's still somewhat easy to find one with firmware that's 3.0.0 or lower, but know that you won't be able to do much with it for a long while. Piracy is off the table at this point, too, unless you find one with FW 1.0.0.
