The reader functionality was not the point of TFA. If you want a product review, there are plenty, including the prior HN discussion linked in this thread.
That said, I read enough in the HN thread to get the sense of not bothering with “out of the box” and just flash Crosspoint Reader on it. I played with stock for a few minutes, it was functional, but not notable. Crosspoint took ten minutes to flash, and is head-and-shoulders above the stock FW. Better reader functionality, better font rendering.
