Just read Gruber’s review at daring fireball. Really enjoyed his breakdown on the differences between the XR and XS.
Actually what’s very interesting is how the XR uses the wide angle camera (it’s only camera lens) for portrait shots. It ends up getting much better portrait shots in very low light compared to the XS (as it’s using the telephoto lens which has a much smaller sensor).
Essentially what I was expecting. Excellent option for anyone not needing the additional luxuries of the XS (SS, OLED, 3x retina as opposed to 2X4, retina and telephoto camera sensor).
