I'm also probably the only person on here that just ordered the base 21.5 model.
You're not the only one. I ordered an almost-maxed-out 21.5" model.
I don't do professional graphics or video. I have no reason to buy the huge 27" model.
The ONLY option I wish the 21.5" model had was optional high-end graphics card. But even that is a small disappointment to me.... since I am a "light/moderate gamer" at best. If I wanted to do hard-core gaming, I could simply buy a cheap desktop PC.
