TheStu,
I'll agree with that. However, ScottyB said some key words for his application: "high light environments." That being the case, a matte screen would better represent his work than a glossy screen, in my opinion. But like you said, he should just see them in person and make a decision.
ScottyB - if you're only going to be presenting while the laptop is plugged into the charger, then a glossy display might be fine for you. At max brightness, the screen is highly visible. Your battery will die quite quickly, though, if you're not plugged in. I would especially get the matte display if you plan on showing off your work out in the open, as opposed to one-on-one, because then it's visible from more angles than a glossy screen.
Food for thought: this is my first glossy screen. It's not that bad, really. There are some things I like about my previous matte screens, but overall I enjoy this one better. The LED backlight is quite good and view angles are WAY better than my previous laptops. My favorite thing about this glass shielded screen is that it's easily cleaned with Windex and a paper towel! I mean 100%, streak-free clean. Love it.
