MacBook Pro 13 or MacBook Pro 15 Retina?

Question

macbook

Hello everyone, this summer I am going to buy a MacBook Pro Retina, but I have not decided on 13 or 15 inches.
Here are two candidates: MacBook Pro 13 Retina Core i5 2.7GHz
/ 8GB/ 256GB SSD - 96,500 rubles
MacBook Pro 15 Retina Core i7 2.5GHz/ 16GB/ 512GB SSD - 136,000 rubles
after filling it with water and taking it to repair, I thought about buying a new one - of course I'll sell Air later - the choice fell on the "pro" series, since I sit at the computer for 10-12 hours for a very long time and my eyes get tired at such a small resolution.
I am a 2nd year student, I use quite a lot of Microsoft Office, sometimes I program, I use Adobe Audition 1.5, sometimes I use Photoshop for myself, because of specific study programs, I had to install Windows through BootCamp and install the ANSYS program, what programs will we be loaded with in the future unknown, I also want to completely change from a regular PC to a laptop. Portability is needed, but it seems like 2kg is not so much (if you take 15 "), especially if you put the laptop in a backpack. Autonomy is also important, but even here, according to the declared characteristics, both laptops have good performance.
But all my life I adhered to the rule, it is better to overpay and buy more powerful hardware, which will last for a long time, roughly speaking, "The miser pays twice." With regard to the Pro 15 "I am tempted by the presence of a discrete video card and 16GB of RAM, with respect to the Pro 13" compactness, but since now, due to the dollar exchange rate, the prices for these "laptops" bite very much, I'm waiting for the advice of experienced "mac drivers"! Is it worth saving up for such a handsome man as the Pro 15 "? Is it worth the money? Is it convenient to carry with you? According to the filling, it is clearly enough for a long time. And I take a laptop until the end of training, for about 4-5 years. I am very interested experience with these laptops
Help!

Answer 1

I am writing with 15 "pro (I bought it in January 2014, the flight is excellent, I traveled with me many different countries). I think it's worth my money, but it can be stressful to carry it, after all, the laptop itself is 2kg + often you also need to carry a charge, and there are some other things in the backpack. If mobility is important, I would definitely take 13 "(it also seems to have a long battery life).

Answer 2

At the 15 pro itself, it’s not very annoying to carry because most of the movement by car ..

Answer 3

I have a custom assembly 13" / 1tb / 16 that fits into backpacks in a special compartment where 15" won't fit.
Now there will be a new version and I will take 13 ", and I want to sell mine from him with a guarantee until January 2017. Under warranty, they changed it because of the touchpad - topcase (Klava + battery + touchpad + part of the case).
It is convenient to work on an airplane on 13" , the battery on video viewing holds 7 hours, since it is zero).
