I use it all the time. It does exactly what I need. I'm usually either a one man dev team or the only experienced person in the room and I don't have the time or resources to do all the work that docker requires of me. I've been to a bunch of docker meetups because everyone loves the thing but it just seems like a hassle. I tried switching 3 times (2014, 2015, and 2016) and aborted each time after a couple days of grief.
I posit that people who use and love docker have larger teams with proper full-time admins and not just 1-3 people wearing all the hats. This is fine. I just have to be super judicious with my time.
I've also heard that many of the benefits come if you have a lot of servers running that are talking to each other. I'm not really doing that. There's also supposedly some lower overhead costs in using it but 32GB of ram which is nothing special these days has been more than sufficient for my virtualbox needs; heck I usually have 28 or so left over.
Vagrant+virtualbox I use all the time (here's the vagrantfile I am currently using: http://9ol.es/Vagrantfile - no chef or puppet stuff I just do it manually) . It doesn't do much and that's perfect, just what I'm looking for.
