13-inch rMBP is light and very mobile but the 15-inch screen makes it very viable. For some iOS app development and some web development which model of the latest rMBP would fit better?<p>Memory upgrade to 16GB seem to be a no-brainer. The extra ~ $500 for the 15-inch is something that's worth to consider. Don't wanna spend on something that's not really needed.<p>Which of the latest model MBP would you recommend for a reasonable iOS and web development?
Are you going to be doing graphic/web design stuff yourself?<p>If Yes ----> Buy a 15" rMBP<p>If NO -----> Go to a store, look at a 13" laptop.<p>Is it too small?<p>If Yes ----> Buy a 15" rMBP<p>if NO ----> Buy a 13" rMBP
I'm currently with rMBP 13 and I'm using it mainly for web development, as UI/UX stuff also.<p>The screen size is not an issue for designing; you can switch to more space, e.g. when designing I'm switching to 1680x900 and don't feel claustrophobic as on my previous MPB's 13".<p>I had high-resolution & anti-glare MBP 15", just before buying the retina, so I'm comparing it with the 13" rMBP and actually the retina feels more comfortable for designing stuff. Weird, heh?<p>I would max out the ram and SSD and go for the 13" model.
The big benefit of a small monitor is that in the long term is forces you to be uber productive with the keyboard. You'll probably get more short term value from a 15" but more long term value from a 13". My keyboard mojo went through the roof when I switched from a 17" to a 13".
Something to consider: Xcode's UI, particularly for editing Interface Builder stuff, really benefits from a larger screen.<p>On a smaller screen (13" or 11"), you'll find yourself constantly toggling panels on/off so that you can see what you're working on.
For web development a MacBook Air will do just fine, even with 4 GB RAM. Screen size shouldn't matter, you're probably going to hook the laptop up to an external monitor anyway.
for development, i think they're all the same. I prefer the 13" because its more portable, or the Air for better battery life<p>For design, the 15" would be nice
