I have found that many people have problems with SP2. But fortunately for me, so far, I have had absolutely no problems with my SP2. I have no problems with Wifi losing connection constantly. I have no problems of excessive CPU utilization. My SP2 will not wake up alone from sleeping mode. I have a SD card inserted and never had any issue. My battery lasts about 10 hours with a custom power plan. The only thing I don't have is a keyboard cover. Do you think that might have something to do with it?
