Okay, we went over this a while back, and it was finally deemed that the glass doesn't really add anything at all, and could actually be detrimental to the picture very slightly since it's another object for your eyes to look through. The monitor was originally designed without the glass, until hazro tried it out and decided it looked 'cool' and made the monitor look more expensive. Make of that what you will. The dust problems are fixed, but the glass screen really does add a crapload of reflections. Users of it on here don't really mind it, but I think they expected it so became tolerant. Some wish they got the non glass. The only pro of the non glass I can give, is that it'll prevent dust getting into the gap of the bezel, but then again, I still can't fathom how with one guy the dust actually got behind the screen and was visible. As far as I'm aware, due to the way the screens are made, that shouldn't be possible at all.
All in all however, I'd still go with non glass. The reflections are almost eliminated when displaying images as the LED backlight is far brighter than the reflections.
And dear god, someone please buy this monitor ASAP and comment on the issue please. I really wanna buy one this week because of the price drop.
