I have decided to buy an imac. I am unable to decide between the 20" 2.66 GHz & 24" 2.8 GHz I have been too the apple store and checked out both - I know the 24" display is better than the 20".... Appreciate your suggestions ... My Needs..... * Personal use - self and family including kids. * Intend to use my imac for web browsing, ms office apps, photography (amateur), making personal videos using ilife and burning DVD, music.. Want to buy VM ware and install Vista / XP later... * Would 24" adversely effect my kids eyes compared to 20" - my kid is short sighted & wears glasses. I live in an apartment and plan to keep the imac in the living room corner - will have a viewing distance of 1.5 to 2 feet from the monitor * Max hours of continuous use - say 3-4 hours.
