Turn up the brightness of the display will help. A glossy display reflects if the background is brighter than the display.
As a matter of fact, every screen reflects. This reminds me a story that happened years ago with a CRT monitor. At one time, we bought 4 PCs for the office. Looking into a monitor, we could see a horizontal line near the bottom of the monitor. The sales lady exchanged the monitor. The same thing happened on the second monitor. When she was about to send back the second monitor for an exchange, a wise elder man came into the office and noticed that the horizontal line was purely due to the reflection from a window. We then moved the computer to a different place. The horizontal line then disappeared.
Having told the above story, I'd like to say that Apple screens are good ones when you avoid a bright background. I currently have a 27" Cinema Display. At its price level, it is the best display in the world for ordinary uses! Surely, there are much better displays for professional uses!
