OLED makes sense. OLED requires no back-lighting, like current LCD displays do. OLED is therefore compact, reducing the form factor. OLED uses far less power, extending battery life. OLED requires no borders, so it will truly be edge-to-edge, increasing the display width to match the keyboard width.

Samsung's product is rumoured to cost an extra $2,000 over an equivalent laptop with an LCD display. Production is low, demand is high and marginal production costs are very high. Sony is working on production technology that may reduce costs.

As for this see-through business: it is useless gimickry.
