Why has the market given up on 1920x1200 laptops?

[mephisto]

Been researching for a few days and am incredibly disappointed at how there is absolutely no choice in the high res laptop market. HP doesn't have one, it seems like Sony doesn't have one. When I walk into a future shop/best buy/sony style, they don't have one.

Basically Dell is the only game in town. Anyone know why is that? I thought we lived in a market economy with healthy competition....
