Hey, I recently purchased a new 13in rMBP and this is my first mac computer ever. When I use the macbook in bed on my lap, my wrist and my forearm really start to hurt from using the trackpad, especially the 2-finger scrolling. I was wondering if anyone else experienes this as well and if I'm doing something wrong to cause this? I had a similar problem with my previous HP but I figured that was due to the horrible "trackpad" on it and where it was positioned. I thought this problem would go away since MacBooks are known to have one of the best trackpads on the market. Thanks!
