The problem for me is that I very rarely just listen to things. I'd rather watch videos and usually the ones I like most are not there. If I want to listen without watching, like when I'm at work, I play full albums either on my phone, or on YouTube.
As for keeping in touch with people, honestly, I'm active on six different social sites and forums. I communicate more than enough, I'd say.
Same here, really. I watch Youtube for videos and have an MP3 player for everything else. Sound quality is rubbish on my home PC (although good on my tablet), and we have no sound at work.
