Edit: The software key has been given away.

I recently bought an Intuos Pro Medium and have no need of the bundled software. I don't know exactly which kind of software it comes with as it seems to differ regionally. I only have the one key so it's first come, first serve. sMail me if you're interested :)

Would it work with the other Intuos tablets?

It's not tied down to any particular model. Unfortunately, someone else has already inquired about it.
