With the MacBook Pro Retina 15" just receiving a minor spec bump, I am tempted but hesitant since it is still using the Haswell chip and that Skylake is reportedly bringing some major improvements and a redesign. I am currently using the base MacBook Pro 13" Mid-2010, which has been upgraded to 8GB RAM and 128GB SSD. I have just completed my first year in Engineering, potentially majoring in Systems Engineering next year. I am currently doing some web development and design, learning Android app development, refreshing myself in Java and C, and picking up some new languages such as PHP and Phyton. Although I am doing a Solidworks/CAD project right now, I just can't do it on my current MacBook as Windows is installed on second hard drive in the optical bay position, which is just too slow to run anything smoothly. I am also worried the integrated graphics can't handle it. If you are in my position, would you upgrade to the 15" now or lug the current Mac, use the school's computer and wait it out?
