Picked up a SP4 core M yesterday and am very happy with it so far. I previously had the i3 SP3 and this machine feels much faster and snappier than it did. One display driver crash so far but none since I modified the host file. I do every so often get a strange popping sound. Overall I am verry happy with the SP4 and the core M processor. My use is mainly web surfing, watching video, email and office type documents. Every now and then I edit 1080p video from cycling cameras but that's about as heavy as my workload will get. I like that it's fanless and I have not noticed it getting hot. Heck it barley even got warm when doing all the MS updates. Anyways with all the negative threads going on I figured I would post a positive thread on my SP4 core M experience..
