Looking for help to decide what laptop I should choose. I've been waiting since WWDC 2012 to get a rmbp. I was so sure back then that I wanted/needed a 13 inch model. I was disappointed with the specs and benchmarks of the 2012 rmbp 13 so I decided to wait for next gen. I was glad to see that you now have the option to get 16GB RAM in the 13 inch and that Iris provides much better graphics. However the Quad core is still only in 15 and I'm still a bit sad that benchmarks show that the 15 inch destroys the 13 inch in score. I'm going to use it for work. I do software development(Java) 25% of my time and email, skype, manage linux servers for the rest of the time. The main tool for me when developing is IntelliJ and it's much compiling and running application servers locally. Many of my colleagues have the 2012 rmbp and it's a bit crazy how fast that machine is. I have one colleague that have the 2012 rmbp 13 and he kind of stated that the 15 model is much better for dev work. But he is doing dev work 100% of his time. Currently I use an Asus U36S with a none SSD harddrive, Intel Core i5-2430M 2.39GHz Sandy Bridge processor and 6GB of RAM. Geekbench 3 give it 1319 in single core test and 2681 in multi core test. I use my laptop in a pretty mobile way. Many meetings, bring it home and use it in the sofa or bed. When I switched from 15 inch to 13 inch a couple of years ago I really loved it. I promised myself that I would never ever go up to 15 again. It's just perfect size, however when doing programming it's too small to get a good view of the code. I use an external monitor at work however I have to do dev work also when I'm home so it would be nice with more space on the screen. The Asus support max 1366x768. It all comes down to if the 13 inch if fast enough for dev work and if the 15 inch that is very thin can be a very portable laptop. Would be very interesting to hear from any of you that have been in the same situation and bought one or the other and how you felt afterwards.
