I used to be a die-hard Thinkpad fan and especially loved the matte screen that came with most models. Then my previous employer forced a glossy screen Presario on me and I had no choice but to accept the change.
Things were frustrating for a while, but then I realized that the glare was the only drawback and I had subconsciously learned to get rid of it by adjusting the angle of the screen.
Once I was over that hurdle, things were a lot more comfortable. The sharpness, vividness and brightness were much better than any matte screen I could find.
