Hi, Background: I am a development manager and software architect. Typically deal with multiple projects simultaneously, hence need around 50 Chrome tabs open all the time, one single VM, MS Office apps, Skype. Some days when at client site, I ideally need at least 9 hrs battery life on such workload, at 50% brightness. I have a few questions: 1. Did you so far hit the 16GB RAM limit in terms of performance degradation due to swapping? What type of heavy workload can it take until performance starts to affect negatively? 2. Does the keyboard area and/or underside get uncomfortably hot under heavy workload? 3. If you have used entry level model of 27-inch iMac Retina first gen, how would you compare the day to day performance (like zippyness) of MBP 2016 with that of the iMac Retina? 4. Does the bigger trackpad cause unintended movement of cursor while typing? 5. How has been the battery life *after* 10.12.3 beta 4? 6. If you have used it with LG 27UD88 4K monitor, have you experienced any issue? 7. If you're coming from a 12/13 inch rMB/P, do you find 15-inch's weight or size inconvenient? Many thanks to the responders! --- Post Merged, Jan 18, 2017 --- If anyone has more questions specific to 15-inch models, feel free to add to this thread.
