The past month my neck has had this kink, I can't really turn my head in certain directions and I think it's because of the way I work on my computer. My right shoulder, right where it connects to my neck feels extremely sore, especially when I lift it to use my mouse. I have a MB and it's only slighlty raised by some books under it. I think it's a combination of me constantly looking at a downward angle and my right arm slightly higher than it should be. I had an eMac before this and didn't encounter any problems. I don't want to get a new desk, but a new chair with a height option would be doable. You guys got any tips? I was also thinking of gettin a stand for my MB, any cheap ones? There's the mStand for $50.
