I know that this topic has been discussed ad nauseum, and that it ultimately boils down to personal preference, but I haven't seen the question asked in the context of what I'll be using a MBP for. I was recently downsized from my company after many years. I've long thought that, if it ever happened, I'd like to start my own business. As I search for another job for the short term, I'm doing freelance writing, editing, and PowerPoint presentations, which are my bread-and-butter skills. I'm also learning front-end web development and probably will do some of that on a freelance basis. My long-term goal, though, is to have an online business built around a blog and sales of digital courseware and related products. I'm thinking WordPress for the blog, LearnDash for the courseware, and other necessary plug-ins. I anticipate eventually doing podcasts and short online videos, and of course there will be photos -- all the multimedia elements that go with a website. I'm also an enthusiast photographer, and I use Aperture, Adobe Photoshop Elements, and onOne Perfect Photo Suite for organizing and post-production. My main question is whether to go with a 13" or 15" rMBP. I'm currently using a 2012 2.3 GHz i7 Mac mini which, until recently, was our home media server, and which I'd like to return to that duty. I'll be using an external monitor much of the time, but I like the flexibility of being able to work elsewhere in the house, on the deck during nice weather, and occasionally off site. So, for web development and the other needs I mentioned, how much nicer is the extra real estate of the 15", vs. the trade-off in price and portability? Next is the processor. I suspect that a 13" with dual-core i5 and Iris graphics would be sufficient (I'm not a gamer), and that a 15" with quad-core i7 and Iris Pro and the dGPU would be "nice to have." However, since I am talking about business use, would the latter be "highly recommended" rather than "nice to have"? From what I've read, the dual-core i7 isn't worth the extra cost on the 13", though. Finally, storage: 256 GB or 512 GB? My iTunes and video libraries are on an external drive connected to the Mac mini. My Aperture library (130 GB and growing) is on the mini's main 1 TB HDD. I'm hoping that the upcoming Apple Photos app will let me keep my photos on a network drive and in iCloud so that I can access them from any device. If not, I could put them on an external drive, but I'd rather keep them on my main computer (i.e., the MBP). Also, there's the possibility that I'll need to install Windows in Parallels for some client work, which I understand tips the balance in favor of 512 GB. If I could get by with 256 GB, though, I'd prefer to save the money. I always buy refurbished to save money, so I'm not going to worry about waiting for Broadwell. The options I'm considering are the 2013 13"/i5/256 ($1,159), 13"/i5/512 ($1,409), 15"/i7/256 ($1,489), and 15"/i7/512 ($1,979). The high-end 15" also has the advantage of 16 GB of RAM and the NVIDIA GT 750M. I keep my computers for as long as they're useful (I still use my 2008 15" MBP for light-duty stuff), but for business, it might make sense to upgrade more frequently. So, you other writers/editors/bloggers/web developers: which MBP do you use and recommend? I don't want to spend more money than I have to, but an $800 difference between my low-end and high-end choices isn't that much, when you're talking about a business tool that will last for several years. What appeals to me most about the 13" is the portability. What appeals to me most about the 15" is the extra power (but do I need it?) and screen real estate (which of course is mutually exclusive with maximum portability). Again, I've seen several variations of this discussion, but they've been asked by people with different needs (heavy gamers, pro photographers and videographers, casual hobbyists, programmers running multiple VMs, etc.). In case anyone wonders, I have considered a 13" MacBook Air, but, for me, the 13" rMBP offers a lot more for not much more money. I've also considered a 27" iMac, but I like the portability of the MBP, and I can attach an external 27" monitor to it.
