I bought a new 24 inch wide screen LCD monitor that arrived today (very late today), I replaced a 21 inch LCD with it. I also have a secondary 15 inch LCD.
The extra screen space that a wide-screen monitor gives you is simply amazing. At 1900X1200 resolution I can have my development environment and a debug screens open on the 24 inch monitor and email and IM on the 15 inch monitor. No flipping between apps trying to find what I need.
What’s interesting is how much more useful that horizontal screen space is than vertical screen space. It’s easy for me to scroll an application vertically – not as intuitive to have horizontal scrolling that is useful. Think about the way we read – top to bottom, left to right – but always scanning down more than over.
A wide screen monitor just feels more natural to me. You should try it.
