Got a hold of an ipad last night. I started using it and after a short time I had a killer headache. It came on much faster then when I use a MBP with a glossy screen. I should have known that was going to happen. I had to switch to an anti-glare MBP which made all the difference in the world. My question is about the anti-glare (matte) screen protectors. Are they all basically the same? That is all of them that specify that they're anti-glare. I'm also wondering if they're going to make enough of a difference for people like me that have a real problem with glossy screens. For me it's not just preference. Glossy, no matter what the brightness, room lighting or screen angle gives me killer headaches every time. I have found ways to increase the time before the headaches set in but they come every time. My 17" anti-glare MBP is perfect. Just hoping to find a way to be able to use the ipad.
