And I cant tell you how many distractions I’ve had to face while coding a website. There isnt a bigger setback than staring at your code trying to figure out why IE has one div 3px to the left and firefox is throwing it 2px to the right, and then getting a phone call on ‘visit’ for an update. It upsets my sitting position, breaks my concentration and focus, and I’ve also likely lost my place or forgot what value I just changed around to test. If only there were a way to let people know that you are ‘in the zone’ and wont be available until the problem is fixed or you’ve decided yourself to walk around and think about the issue.
