So I'm thinking of buying the 27" imac. I'm going to use it for web design, iphone programming/animating and video editing. There will be days I'll stay at the computer for around 10 hours, maybe even more. My current monitor is a 19" with an anti-glare display and in 2 years I haven't got any problems with my eyes for staring at the monitor for long periods of time. I can provide darkness in my room by closing the courtins so that there will be no reflections, but many professionals complain about their glossy cinema display damaging their eyes if they stare at it for long periods of time. There's no place I can go to actually see an imac so I'm going to decide whether I'll buy it or not by reading your opinions on this topic. Please leave a reply only if you own such an imac and use it for similar tasks or know someone who does so.
