OLED displays are still planned for the iMac and MacBook Air, but don't expect either upgrade to arrive in the near future. The current 24-inch iMac without OLED Apple's "Pro and Tell" special event is forecast to feature the OLED upgrade to the MacBook Pro , among other launches. However, Apple's use of OLED won't stop there, as it still has plans to use it on other less-Pro models.
