Hi, I currently have a mac pro with two 23" displays. I often use the two displays in order to have two documents (Word, Excel, PowerPoin) open - one on each. I am considering moving to a 27" iMac. My question is: Is a 27" screen large enough to sensibly see two portrait orientation Office documents? This is clearly a subjective question so I'd welcome any opinions - especially from people who have moved from dual monitors to a single 27" one. Thanks, Julian.
