Do you think we could ever have that future?

That's interesting, but personally, I don't see a lot of point. I'm totally willing to learn about other people's workflows and use cases though. I just have a hard time envisioning a need for two pointers at once other than edge cases like resizing lots of windows or something. Maybe 3d modeling, for better moving/rotating control?

In most cases, it seems like the way to get more efficient is to stop using the mouse and fire up a terminal. If you just want more buttons on your mouse so you can have a full keyboard, maybe try the Azeron Cyro? I haven't used it personally, though I do use their Cyborg for games.
