I have a NL920 and an 8x and over the course of the last week have updated both to GDR2 and I gotta say, I can hardly tell the difference on the HTC 8X between GDR1 and GDR2 whereas on my 920 the difference is worlds apart. HTC is getting comparatively worse in all of their markets because they stopped supporting their devices like they used to. It's pretty sad to see them fail miserably as a company now but when you stop innovating and can't market your lack of innovation, you're quick to fall down the totem pole.
