For the first time, I'm at a loss as to which computers I should use / buy. So, I'm hoping to turn to the fantastic MacRumors community for some help. A little history: I've had both a desktop and laptop since the mid 90s. For example, I moved to Macs in 2004 -- with a Power Mac G5 and a 17" PowerBook. Then, in 2006, I moved from the PM G5 to the first gen Mac Pro. In 2010, I moved from the 17" PB to a 2010 15" MacBook Pro. And, lastly, in 2012, I moved to the new 15" MacBook Pro Retina (old MBP broke) and 27" iMac (because the Mac Pro was long in the tooth) -- both are BTO and fully loaded. Current usage: I own a marketing agency and use my computers mostly for work, watching some movies / TV shows, listening to music, etc. Mostly, it's reviewing / annotating large PDFs from my designers (comparing documents on screen), doing some work in Adobe CC (Photoshop, InDesign, etc.), occasionally editing client films in Final Cut Pro X, coding on web development, and the requisite MS Office time. And, of course, lots of emails, web browsing, and iTunes time. The issue: I used to purchase a desktop and laptop because I felt I got received longevity that way. With a Mac Pro, I got to use it for a while for all the heavy lifting and the laptop is only really necessary when visiting clients (2x per week). The 2012 iMac is just too similar in performance to the rMBP that I have and I was wondering what my next steps should be. Which of these scenarios would you recommend: Keep my current 2012 15" rMBP and upgrade from the iMac to the latest 2015 27" 5K iMac. I don't need more portable speed, since I don't do video editing or a ton of Adobe CC work on the go, but I would like get the boost when I'm at my desk. Love the quality of the iMac display, but hate that it is attached and was hoping for something bigger than 27", but not so big as added another display. Keep my current 2012 15" rMBP and upgrade from the iMac to the next generation Mac Pro (whenever that comes out and likely something smilier to current 6 core). That would give me more longevity on the desktop side, but the new Mac Pros are expensive and may be overkill for me. Although, it would give me the ability to get a larger monitor, like the LG 34UC97. Upgrade from both current systems to a new 15" rMBP and just buy an external monitor like the LG34UC97 and external Thunderbolt dock from OWC. But, I'm concerned that the lack of ram would be an issue (I multitask like crazy and it's not usual for me to be working on several Adobe CC programs at once or the occasion FCPX memory hog). Sorry for the short novel here! So, which of these options would you recommend? Is there anything that I'm missing from my consideration? Love the iMac displays (colors pop nicely, good uniformity, no noticeable light bleed and I actually don't dislike the glass surface), how does the LG34UC97 compare in your opinion? Thanks!
