Today at around 10:30 am, I did the install of the Lync 2013 client on the Ipad.
At 10:35 am, I did my first video call from the Ipad. Works just fine.
Did also a test on a Iphone, works there aswell. Just download the App from AppStore.
Have fun while I wil be waiting for the Androide version since my work phone i Samsung SIII.
But the one that waits for something will get something good.
