It looks like the only advantage that the iMac offers over the MacBook Pro is a 3.1GHz processor compared to the 2.7GHz processor on the laptop. How much difference is there between those two processors? The most intensive thing I really work with is Photoshop. Also, I leave my computer on 24/7, and I'm actively working on it at least 40 hours a week (sometimes much more). Would the MacBook Pro have any trouble with this kind of workload compared to an iMac? In other words, the MacBook Pro isn't going to break on me after a year of use is it? The iMac is not mountable and I work on a sit-stand desk so it looks like I'm going to be going with the MacBook Pro and then connecting it to a different monitor... as long as it'll handle the work I throw at it.
