Alienware's latest gaming laptop, the Alienware OLED 13 R2, uses a 13" 2560x1440 AMOLED display. This laptop is similar to the LCD Alienware 13 R2, just with an OLED instead of the LCD (which has a higher 3200x1800 resolution) and an updated Intel Skylake CPU.
The Alienware OLED 13 laptop will ship in April 2015 starting at $1,499. The LCD 13 R2 starts at $1,068. This means that the OLED premium is about $450 - but then again it may also have higher specs, so it is difficult to compare. Alienware themselves says that the OLED model will cost exactly the same as the LCD model.
