Amongst the fantastic features of the iPad 2 that have Apple geeks all around the world drooling on their keyboards, the best just might be the mirrored video capability of the iPad 2, as it now features an HDMI out, and Apple has a cable which does video mirroring on the iPad 2, flawlessly.
The new 30-pin to HDMI adapter (sold seperately) is pretty awesome in itself. Not only does it provide HDMI output at up to 1080p, supports rotation, needs to setup or configuration and works with all apps, the Digital AV Adapter also has a USB-in which allows you to charge your iPad 2 even when its plugged into your HDTV.
So basically, what this means is that you can now enjoy HD content now only on your iPad 2, but port it out on your HDTV or projector as well, and you wouldn't have to worry about the iPad 2 battery dying, because using that very same Digital AV Adapter, you'll be able to charge your iPad 2 as well.
The Digital AV Adapter for iPad 2 costs $39.
