If you care about the games, and portability.
Then yes I would buy it,
However if you plan on not updating to wait in line for Homebrew.
1. You cannot play online, link your Nintendo account, etc... This may be a major feature that makes or breaks you staying on a lower firmware
2. You cannot buy digital download games, demos, etc. You can only use cartridges. This isn't a complete downside.
3. You cannot update (obviously) if you want Homebrew on the console, and you cannot update games, even if your friend has a Nintendo Switch and updates the game for you, you still have to update it on your system to play it. Kind of confusing when comparing how the 3ds updates work with the switches.
As far as Homebrew progress goes though, everything is basically going and coming very quickly. Just recently releases like Cage the Unicorn and some other tool (For developers.) Have released, and some people (rumors mostly.) Are working on a flashcart, Homebrew applications, or basically any progress for the system. Just recently a NES Game was found on the console called FLOG. (GOLF Spelled backwards.)
However any Homebrew apps that can for example, launch the equivalent of LumaCFW for the 3ds. May take awhile (a long time.) to develop. So I wouldn't jump to conclusions yet if Homebrew will come out for just a general audience, although I can guarantee you its happening basically.
But I wouldn't buy the Switch alone just for Homebrew.
Edit: Oh and I forget, its not possible to downgrade or your console basically self destructs its self, due to Efuses or something idk.
Currently HB will only work with 1.0.0 - 3.0.0 as far as I know. Anything above 3.0.0 currently will not work with Homebrew, or at least the exploit the access homebrew.
