My mini review didn't contain photos so here are a few photos of the HP 6910p
Photo of 6910p (left) and nx8220 (right). You can clearly see the size difference of the screen and chassis. The 6910p keys are slightly bigger and full size keyboard, the keyboard layout has also changed. 6910p gun metal gray color is also slightly lighter in shade.
Despite the 6910p being the newer model its front is slightly thicker than the nx8220. The thickness at the rear is however the same. 6910p (left) and nx8220 (right), an AA battery as a reference.
