For what it's worth, the front and rear cameras on Microsoft's Surface products are both high-quality and it's generally a pleasure to do video conferences with Surface users. As some others here have pointed out, it's not necessary to have a high-quality video stream—it's not necessary to have video at all—but it's a better user experience to have a more life-like image of the people you're speaking with. In a group conference in particular, the oddball with the low-resolution 720 web-cam does stick out, looking like a relic from 10 years ago. Especially with a high-fashion status symbol such as an Apple laptop, that's an awkward position to be in.
