Reply to 2 Monitors vs 1 Large Monitor

when producing I use my macbook with a 19" external monitor but now im debating whether I should buy a matching screen or a large screen around 26-30" what does everyone believe?


the thunderbolt displays are cool cause you can daisy chain them but are very expensive and if I were to have 2 screens Im pretty sure I would have to run one with a usb adapter which is just another usb port taken..can you daisy chain the older apple cinema displays?
