Not sure what I paid $80 for. Not much new and I don't see any performance difference at all, although everything was instantaneous in LR5, so I don't know if there was anything to improve on. Just doesn't feel like a version number update, not for HDR and pano and face recognition, none of which I'll ever use. I would have much rather seen curves with the adjustment brush, things like that. Plus my mouse wheel no longer scrolls the right panel in Develop, which is a huge PITA. Still works in 5. And why is there still no folders panel in the map model. What a crazily inefficient design. Sigh. Don't get me wrong. I absolutely love Lightroom. Brilliant product all around. Just thinking this $80 couldn've gone to something else.
