I do not see why it has to ever be an all or nothing when it comes to desks. At work, we have adjustable desks, which can electronically be adjusted to sitting or standing positions. I alternate between sitting and standing every hour or so, combined with small walks around office between shifting positions (say to the cafeteria or washroom or the game room). When I get off my desk, I make it a point to focus on some point far away to ensure my eyes get a break from simply staring at a screen 2 feet away from me. Combining this along with ensuring I consume enough water through the course of the day (in AC environments, a very common cause of headaches/neckaches is simply dehydration) means I can ensure that I get to operate productively through the day. Don't see why people get so paranoid about having to be in a single position for 8 hours a day. The human body simply ain't made for that!
