I know this isn't really a direct comparison as they're both two machines built for different purposes but I was curious to know what you would all recommend. I plan to edit videos using Final Cut X, Motion/After Effects etc. and edit photos with Lightroom 4 (18 MP from a 60D.) Outside of that, I'll just be doing standard lifestyle stuff (web, word processing etc.) I currently have a 2.6/16/512 rMBP on order with mid-July delivery but I'm wondering if I should cancel and just order a 27" iMac 3.4 i7/16/256 SSD + 2 TB HDD with 2 GB video card. I don't need the portability of the rMBP as I have the new iPad to display content and a Mac Pro at work. They both come in at about the same price. Recommendations?
