I am debating between keeping my current 21" 2.5GHz iMac or selling it to buy the 2012 13" 2.9 GHz Macbook Pro, just looking for opinions on what I should do. The issue I have is my iMac is in an upstairs office and is rarely used as we have a windows laptop downstairs that is more accessible. Just looking for opinions from people. I am a relative Novice to the Apple brand, so anything helps! Thanks!
