Put the light source (i have a touch lamp with 3 brightness intensities, i find the lowest is more than enough!) behind the screen like i do with my current screen, should minimize reflections!
The problem is that I often need to read hard copy documents and look at printouts while I'm working, so I'll need reasonable illumination in front of the monitor. I can put a light behind it, reflecting off the wall for more diffuse lighting, but it'll need to be fairly powerful for comfortable reading.
Looking online at the reaction to Apple's Cinema Display definitely gives me cause for concern. While some people love them, there are also a lot of people who hate the reflective glossy display.
I wish there was more information about the properties of the non-glass model, but of course if I wait I'll end up paying full price...
