I'm not sure I would call it "successful" when the capacitive touch screen no longer works.
There are some tasks that you have to you your finger(s) for and the pen won't suffice (e.g. pinch to zoom, scrolling when inking)
You now need to always have a mouse in order to use your "tablet". You will also always need to have an external keyboard as you won't be able to use the onscreen keyboard for 2 handed typing. Yes, you could tap out letters using the pen, but that would be painfully slow.
They've basically converted into a non-touch windows 8 laptop with a digitizer.
