No heat problems with the latest updates. The other benefit of BlackBerry getting the heat under control is improved battery life. I didn't use my phone much yesterday but still had 70% battery after 10 hours.
The AMOLED is also a joy to see. When the phone is in my car mount the display gets bright enough for me to easily see. I can also see the display just fine when I am golfing. Outdoor visibility is a weakness of AMOLEDs so I am happy to report that the Priv's screen is good.
