I am planning on purchasing a 20" 2.4 iMac with 3gb of RAM, but I have serious concerns about the monitor. I will be using it for general web applications, plus InDesign and Photoshop work. While I am not a professional, I would want to have a quality monitor and not have issues with color. (I am a teacher and am in charge of producing the school's yearbook). I currently an using the schools MacBook, but it just isn't beefy enough for the work I am doing.......plus I would like a Mac of my own! Is there a better choice for me in terms of a screen? Am I making a bad decision? Thanks for your insights!
