I let me five year old grandson draw on this last night. I was a bit concerned at one point as he bored down on the pen trying to fill in the whole screen! The pen seems fine as does the screen today. The pen also seems pretty robust and the screen won't scratch with the supplied pen. Anyone have any comments on this? At the moment I'm inclined to let them play as long as I supervise them closely. I'm not about to let them carry it about. It was interesting too watching him master then pen colours and line types in modern OneNote. He nailed it in no time. I was quite surprised but it goes to show how intuitive the radial menu system is and is one of the reasons I use modern OneNote for writing job notes.
