Because of the work that I'm doing just at present, I am using two large computer screens. I had worked with large screens before, they are great for spread sheets, but not two screens.
Such a simple thing, two screens, but a wonderful aid to productivity. Like most of us, I have of a number of programs, browser pages or documents open at any one time, clicking back and forward between them. With two screens, I can keep the main document I'm working on open all the time on one screen, using the other screen for the reference material I need to check or incorporate.
The gains in time and indeed accuracy are quite remarkable.
I mention this here because people's first reaction to the idea of two screens seems to be that it's a luxury. Certainly very few businesses that I have seen provide people with more than one screen.
Now when I come home from the office to my single screen, I miss and want my second screen! Now that's more money that I have to try to budget for!
