Note : it doesn't magically convert .iso files to cartridge format ! It only convert standalone executable (typically, a file that can be executed after being uploaded to 06004000 address), and doesn't support programs that use CDROM.
So, basically commercial games can't be converted, and only some (not all) homebrew programs can be converted.
At work instead of the crappy Visual Studio code editor.
At home in complement with gcc and instead of Quartus code editor.
I also use it to write memo, email drafts, and everything else.
