One of the primary reasons my husband resisted our buying the 27″ iMac for so long was that I rarely worked at the desk. That was due to the fact my shoulders and neck would kill me if I spent more than a half-hour there.
Long story short: I had the chair too high. I liked it up there but, ergonomically, it was a horror show. Thanks to Twitter, I found a comfortable spot, with my knees and elbows making right angles and my neck neutral. I found myself working at the desk a little more and my husband finally realized resistance is, in fact, futile and home we came with the big iMac.
A couple weeks in, it’s not going well. I’ve got the right angles and the neutral neck. I don’t have pain in my shoulders and neck, or hot pokers jabbing between my shoulder blades. But once I get up from the desk at the end of the day, my lower back starts spasming. If I stay straight, I’m fine. But if I bend and then straighten, my lower back freaks the hell right out, just long enough to steal my breath and cause me to make noises that scare the dogs, and then it eases until I bend or sit again. By about 9:30 or so, it starts clearing up and I’m fine when I go to bed.
So I’m curled up on the couch with my Macbook and my dogs, while the iMac sleeps. Just don’t tell my husband.
