Design and form factor
I use a Thunderbolt display at work and wanted to get one for home use but couldn't bring myself to buy a monitor with only one input. This panel, to me, looks just as good if not better. I'm using a mini displayport to displayport cable with 2 MacBook Airs, one with Thunderbolt and another with only mini displayport. I was hoping that the audio would also work through the adapter cable but currently it's not, OS X complains that the "selected device has no output controls". I haven't debugged the issue fully but it's not a huge deal as ASUS included an audio cable that does the job. Still it would have been nice if the audio worked. If USB support was also included it would have been a 10/10. So far this has been an amazing purchase.
