Great device. Looks pretty.Runs hot and if cooling policy has to be changed to make it run cooler, then it runs loud. I switched from my iMac to this for  a quieter experience, but clearly that hasn't happened.Temps on this device really run all over the place - the processor can hit 70+ with under a 5 second 100% load on it and then comes back down almost as quickly. But the kind of stability one expects from desktop class quad core systems just isn't there.I'm using this with a Samsung 950 Pro and 32GB Kingston RAM so the system is super fast,  but I often wonder how an iMac or desktop PC would've performed with the same hardware - both from speed and, more importantly, from thermals/sound perspective.
