I miss my tablet. I had to send it in because the JB update bricked it for some reason. Anyway, I had my Dragon archive on it and was reading through the old issues, I hadn't actually gotten around to doing that yet. I was on issue 38, still a long way until it catches up to my physical collection.
So that's what I miss. I've moved on along with the mags. Blogs, articles and zines do the trick these days. And I can filter to my style easier that way, I doubt there'd be many OSR articles in a current Dragon mag, so I wouldn't be picking it up, and would miss out on any articles that would interest me. But if WotC posts an article online, I can check it out if I want. So I personally prefer it this way.
