My life both, personally and professionally, has been changed by simply adding another screen to my workday. Yes that is right, completely changed.
I, like many others, am prone to intense feelings of anxiety and A.D.D., not because I have a disorder, but because who wouldn't get stressed out and distracted by constant incoming emails with links and attachments, opening up new windows and new applications that just pile up on top of one another. It is so easy to get lost, forget what task you originally started to tackle and in general just stay sane!
Anyone who works on a computer - I don't care the industry - should have two screens at work. Office managers, public relations professionals, sales rep's, you name it - should all be given the opportunity to be more productive and efficient. Let us multi-task in a way that allows us to seperate our spaces. Apple's "spaces" feature on Leopard is starting to address this issue, but a much better solution remains... give us more screens!
