Just got this product today and just thought I'd let everyone know who is thinking about buying it that it doesn't make much difference in temp at all. I haven't even seen a decrease yet and I've been using it pretty heavily for a couple of hours and its been sitting around 80 C for the whole time. The only advantage I see is that if you want the laptop on your lap, the pad can make it more comfortable. I've only tested it on a desk where the heat can pretty easily dissipate. Maybe if I were using it on just my lap or the couch I would notice more temperature decrease. Anybody have any positive experience with this and a unibody MBP?
