Total gimmick. Have one on my work laptop.
Let's look at the use case:
Your fingers are typing and the touchpad is leveled with your hands already. Your choice:
1) do you lift your hand and point and touch at the screen?
2) move your hands slightly and use the trackpad, which is more accurate
I choose 2.
Windows and even Samsung's implementation of the touchpad isn't as good as Apple's. So I can see why people want to use the screen for scrolling a page (2 finger scrolling in Windows does not hold a candle to Apple's trackpad).
Also, when you use it to select, the screen moves when you touch screen.
Versatility? There are three types of these. A detachable screen. This is ok..The desktop is just not made for touch inputs.
A screen that folds backwards. This is the worse. The keyboard is in the back? So you're resting the machine on its keyboard when you put it on the table. Or when you're holding it, you're mashing on keys.
A screen that rotates and folds over the keyboard. Too thick.
It's too much of a gimmick. Using it in a traditional setting makes the screen and hinge move backwards. The OS is okay at best with the touch controls. The unit is too thick to use as a tablet when you don't detach the screen.
