I have to disagree big time here, IMHO they finally fixed it !
And even better, you can now use AppleTV as an INDEPENDENT EXTENDED DESKTOP via AirPlay :).
The only downside is that apps can't span multiple displays when using independent desktops.
I guess you haven’t used windows multi-monitor for a long time. No muss or fuss two full HD monitors side by side.
My early 2011 get’s tied up in it’s underwear using netflix pretty regularly, freezing and showing a blank screen. It happens when closing the clamshell then re-opening it.
Also only one external monitor is allowed unless you buy a $300/400 gizmo or an apple monitor.
