Programming is a long and complicated journey.
(But so is learning to sew or play an instrument,
or any kind of hobby that involves learning a skill.)
The important thing is that it can be really fun,
especially if you like puzzles and problem solving.
It's also very rewarding, and it can be very eye opening.
It's hard to say whether programming the Pokitto specifically is easy or hard because it will depend on the difficulty of what's being programmed and the skill/aptitude of the person,
but it's no harder than any other neo-retro game consoles and the important thing is that there's plenty of people around to help if you get stuck.
...I could imagine the Pokitto with a razor attachment.
If you don't mind, since this post is sort of your introductory post I'd like to move it to the "introduce yourself" area.
