Okay, hope this doesn't sound crazy, but I have the Aluminum Macbook and I have a suspicion that it is causing giving me nausea from staring at the screen for too long. I'm a programmer so I've stared at lots of screens for a long time and can play CounterStrike or Wolf3D for hours without problems. But I don't know, I don't feel right after using my Macbook for a couple hours, even with frequent breaks. This is my first Macbook I've owned, I've used a matte screen iMac before. My previous laptops have all been glossy screens. Anyone else have problems with this? Perhaps the backlit and glossy is a bad combo for me? Maybe something wrong with the refresh rate? Well any advice or stories would be appreciated!
