OLED will come. It's just now finding it's way into TVs, and still costs a fortune... When you think about it, a 5" OLED screen comes in a 700 dollar phone, most PCs cost that. Not many people would be willing to pay 2000 for a laptop with an OLED screen. Some people maybe, I know I would, but most wouldn't.

I think in 2-3 years you'll see Samsung Chromebooks and Ultrabooks with OLED screens...
