I admit that I use my macbook pro's 80% while lying down, 10% on couch, and 10% while on my thrown jk hehe Kidding aside, I do mostly use my rMBP while lying down. Just wanted to ask if you guys use a pillow to put it on top of your body while lying down? I try to position the horizontally or parallel to my body so it will not block the vents on the side. I may even have to purchase one of those cooling mats but to only use it as a platform. What do you guys do? Also, for those with a Kuzy or similar hard case, would this further help to give more clearance off the pillow? I'm sorry if my thread may seem silly but while I was watching a flash video earlier, the fan speed reached to 4500 and really warmed up...I guess I have to ditch the pillow for now.
