My neck is ok. I loosely follow all of that boring ergonomics advice where your eyes should usually be in line with the top of your monitor, have an appropriate adjustable chair, don't just work on a laptop screen get a proper monitor with a stand and keyboard and mouse in the correct positions, you should be able to comfortably put your feet on the floor, etc. I'm not in that position 100% of the time, sometimes I like to be able to lean back and stretch my legs out a bit, etc. and I do use my laptop screen as a second screen. The 'good ergonomic posture' position is just the default position I have my desk configured to. edit: another thing that I might be missing here as well is that I try to walk a decent amount as a part of my daily routine and get at least some (albeit sporadic) more intense exercise in as well. But during walking I often make a conscious decision to fix my posture which I think goes some way to maintaining an ok posture at my desk as well.
