The good: you can hack your switch day 1 using a very simple one-step process.
The bad: that process is "swing your axe at the switch until it consists of as many pieces you want".
The good: nintendo might include a "press this button to automatically hack your switch and start downloading our entire catalog for free NOW!!!
"
The bad: chances of that are less likely than everyone in the world winning the lottery on the same day...today.
The good: the portability of the thing allows you to showcase your 1337 haxxor skillz to your friends
The bad: your "1337 haxxor skillz" consists of lurking on gbatemp and scriptkiddie'ing the work of others
The good: maybe the browser will have a day 0 java buffer overflow error that could lead to low-level access to the switch registry where you can bypass main security to inject programs with loopholes so you can run unsigned stuff on kernel level.
The bad: the last sentence is just a bunch of regular hacking terms thrown together to make me look smart, while the "maybe" word at the start neatly conceals the fact that I don't know what the fuck I'm talking about.
