Hey guys, I bought a 27" NEC PA272 monitor to use with my rMBP recently, and now I don't know if I should return it and get an iMac instead. After adding the upgrades (i7, 16GB ram, 512 gb flash, m295x), the Retina iMac comes out to $3600 including tax and AppleCare. The NEC monitor was $1200. Since I'm not experiencing any lag when driving the NEC off my late-2012 rMBP, the only reason I want the iMac is for the screen, and I don't know if an additional $2400 for a prettier screen (and computer) can be justified. My uses: - programming (80% of the time) - photography/video (10% of the time) - web browsing and other non-intensive things for the remaining time Does anyone have any thoughts? Are there pros/cons for desktop and laptop vs. laptop and monitor? The pros I can see from the NEC are the color accuracy and the lower price (without considering that the iMac is also a computer). As for the iMac, are there noticeable differences when upgrading to the i7 and m295x? I like the flash memory since it runs cooler, is faster, and is quiet. As for the ram, I don't even know if I'm using more than 8 GB (out of my 16) on my rMBP right now. What would require more than 8 GB? Thanks!
