What would make more sense for me? I've had a white macbook since June 2007, And I'm looking to upgrade some time over the summer when Lion gets released. I have used a 13" macbook as my main computer for 4 years now 90% of the time sitting on a desk, and every once and a while I will play downloaded movies to a 32" screen. The other 10% the laptop is used on vacations, and every once and a while used for light browsing when I dont feel like sitting at a desk, on a couch or bed. What would make more sense? Upgrading to a Macbook Pro and dropping $2,500+ on a 15" or Getting a 21" iMac for when i'm at my desk for ~$1,500 and an 11" Macbook Air for $999 for the other 10% of the time if I think I really need the portability later on? Current set up: 120GB HD 2.16Ghz Core 2 Duo and a 500 GB External Drive for movies and a 250GB external for Music, both almost at their capacities.
