Manufacturers wonder whether to build widescreen (16:9, 16:10) or standard (4:3) displays. The widescreen format was introduced because our field of vision is wider than tall and cineasts were annoyed by getting distracted by things that went on left and right from the movie screen (be it cinema or TV).
The computer industry followed soon. I am using a single 21” widescreen TFT Display and boy do I like it. The only way I would go back to 4:3 is a dual display setup. For example, the last entry was written with TextMate using Markdown:
On the left, I have the editor window open. Next to it the preview window, just because it is so nice to look at. And next to that is the Markdown syntax cheat sheet. I’ve never written an entry that fast! When I write papers for the university I use LaTeX instead of Markdown, but the setup is basically the same. When I do web development the setup is basically the same.
The wide space allows to have all necessary information for a task displayed at once while filling it up enough to help me focus and not get distracted by other things.
Go Widescreen!
