I think about buying a Surface Device. But I am not sure if I should buy the new Surface Pro i7 16GB Ram or the Surface Book with P.B. i7 16 GB Ram dGPU, because with the Student Price the Surface Pro (with keyboard and Pen) is only around 200€ cheaper than the Surface Book. I will use the Surface especially for CAD (Siemens NX, Pro/Engineer, Rhino3D) and One Note, and I will buy a Docking Station for using the Surface as Desktop PC. Now my Question: What do you think? Which Surface will have the better performance and graphics performance, especially in CAD? I ask because I am not sure if I should buy a hardware, which is nearly a year old. Maybe the Surface Pro is better, although it has no dGPU. But I think you have more know how than me. Sorry for my bad english.
