That looks like the one. I get why it's not really been replicated. Making a UI function well in both touch and keyboard and mouse modes is hard, the extra space you need for touch is wasted in laptop mode and then you're asking every app maker to support another UI mode which gets into the chicken and egg problem of support. It's not every useful without apps and it's not worth supporting for app makers unless there's a broad userbase or extremely low support costs. The closest we get now is the iPad pro line going in and out of a keyboard case but that's not quite the same and the jump in capabilities is pretty small because the form factors are so close.
