Leopard Feature: External Display Restrictions Gone

iMac and iBook owners who have tried to use a dual-monitor setup have probably realized that they are limited to the display mirroring feature. The extended desktop feature can be used with screen spanning doctor or one of several hacks available online. But wouldn't it be nice if Apple just enabled this feature by default? Seems like they finally did in Leopard. Finally, no restrictions on dual-monitor setups even if your video card is slow by today's standards.
