I already have a Gateway, but i also ordered a Sky3DS (Blue button) for the ease of it, just plug it in and play, another game at just a push of the button and my kids updated the 2DS to 9.4.x and my 3DS's are all at 9.2.x
Yeah Sky3DS only focus is at piracy, but don't all Gateway users also use it for the same piracy? as far as Homebrew on 3DS, there isn't much out there to play (a few emulators (i think 5) a few games and a few applications
Yes there will be more out in the future, but as it stands now, Piracy is the main goal for 95% of Gateway users, while it is 100% for Sky3DS.
Gateway has a broader view with Homebrew, cia files, etc... and all the eshop stuff you can run is also piracy, even if it's a demo!
In the end, ppl will buy what works for them, Sky3DS for anyone with a higher FW then 9.2.x and Gateway/Sky3DS for anyone with FW 4.x to 9.2
Those that want to do more then piracy alone go for Gateway, those who just want to play a game, choose for yourself, only time will tell if you made the right choice, who knows what cart gets the longest support or what cart will
come out in the future with better options!
Look at the NDS carts, those carts that only supported homebrew and no piracy, they came and died soon.
