Hey I'm new been reading the forums to try to help me decide which iMac I should get. New 21 i3 vs refurbished 27 i3. I will be using it for web surfing, watching YouTube videos, storing my music and photo collection 100gb and growing. The reason I was thinking about the 27 is cause of the beauty of it. My only concern is alot of people complain of everything being to small on it cause of the pixies. Any help will be appreciated. Also how will YouTube video look on the 27 full screen. Thanks
