What OneNote's Math and Replay features say about the spotty state of Windows Ink

One of the most significant features of Windows 10's Anniversary Update was the addition of pen computing, known as Windows Ink, which we criticized as falling short of the average consumer's needs. We don't know whether any new inking features will be announced at Microsoft's Windows event on Wednesday (or the event that follows on November 2). Recently, however, we took a deeper dive into the capabilities, when we tried the new Math and Replay features within Windows 10's OneNote UWP app. Math translates and solves inked equations, while Replay records your series of ink strokes and can play them back. But the devil's in the details, and the challenges of both features show how Windows Ink is struggling with the realities of handwriting recognition and data wrangling.
