The price between the new Mac Pro and the Macbook Pro with Retina highest end is not so crazy. I already have an apple cinema LED display. I used my macbook pro 17 inch 95% of the time as a desktop replacement, meaning: on a desk, connected to the biggest 27" screen. So I wonder. Would I find any benefit with the MBP 15" retina? I use it for too many different applications to name a main one. Web, work, video editing with final cut pro (but as an amateur) , lightroom, photoshop etc. It's actually quite portable when you think about it... if I'll ever need to.
