So, I am a recent mac convert and am, thus far, enjoying the new machine. However, as of late there seems to be more heat dispersing from the machine. I have only had it since the 2011 release, and could have just overlooked this until now. I am not gaming or anything near that demanding. Only Safari, Firefox, pandoraboy, Word, and flash (such as youtube and hulu). Sitting on my lap, while in bed, I find myself shifting the machine around to help disperse the heat being it serves as a source of discomfort. It's not burning my legs, like my envy 15 use to, but I am wondering if this is "normal." Please forgive my naivety with this machine; I have always been under the persuasion that mac's were known for their "quiet" and low heat dispensing properties. Thanks for your help.
