Good point. I just looked at Samsung's lineup [1] and it seems they're mostly plasticy machines aimed at the low and mid end of the market. I thought they had some high-end parts like Dell. Guess they don't have the platform to adequately show off the screen quality, so they just cobbled something together.
Samsung is both a creator of consumer electronics (TVs, dishwashers, smartphones, notebooks, etc) and a supplier to other consumer electronics companies. They're massive. Hence my bringing up their notebooks, as I was initially confused that they'd be introducing this in their own lineup.
When you have unique access to technology, one strategic opportunity is to use that to move up the value chain from being a supplier to being a retail brand and create a differentiated product, winning market share. Samsung right now pretty much has a lock on non-TV OLED production, but is choosing not to go the path of using those in their own computer brand, and instead are selling to other computer makers. It's an option they have but have chosen not to pursue... so thats interesting.
