The Competitor series of computers are similar to the duo in some ways.

However, the E model, has completely eliminated usage of scene.my. This means you can have multiple Model Es running at once without interference!
The S model (means slim) has a dedicated monitor, however.

I really like these, especially because you can full-on install stuff on them.

There's not much more room for improvement for now, but I will constantly be brainstorming!

Instructions in scene.

This is the model E, which means the computer and monitor are all in 1 unit. This makes it possible to fully eliminate global variable usage.
