Working with people in different offices, we use head phones every day. I've watched Windows users over the years constantly struggling with headphones and Skype and been very happy to be MBP based and just have it work. When you spend a lot of time on Skype and the like you really come to appreciate the value of good and working A/V equipment. The builtin mic is all part of the package with Apple headsets.
I don't really care if they get rid of the headphone socket, so long as they have a solution. Given that I get my headphones from my iPhone, I wouldn't be happy spending a tonne just getting a second headset for laptop. They also better not make me give up one of my other ports - I often have both USB-3 and both Thunderbolt ports in use, and I'm still left looking for a way to plug more things in sometimes. Ultimately it's a tradeoff but I think Apple has done reasonably well in balancing this up, at least in the MBP line. MacBooks with the single USB-C port that does both power and connectivity has no appeal.
