Do you use your MBP on your lap? or on a desk/hard surface? Okay, so i have an early 2011 MBP, first one was faulty with overheating/shut down issues and for me, this one is still running uncomfortably hot for my liking (between 80-90 degrees). After taking it into Apple today about this and a few other problems. When discussing the heat 'issue' I was told that the macbook pro ranges are not designed for using on your lap, that they should be on a 'hard surface' due to the heat. Mind you apple's website does state that it should not be used on your lap for a 'prolonged period of time' - in my case it can reach 90 degrees 10mins after a cold boot up (is this prolonged?) SO i'm just curious as to how others use theirs, cause i use mine at university, in auditoriums where 'hard surfaces' are not available and your only option is your lap!
