In my quest to maximize value for money spent I've started looking at the 13" models. I had thought I'd stick to the 15" as a way to future proof a computer I'm going to keep for years to come. I see the tech world moving to intense graphics for almost everything. So, while I may not fully use the dGPU or quad core functionality today, I'm wondering if I should by it now for future proofing. Plus, for the money, it seems like the 15" provides more value if portability isn't a primary consideration. I'm not doing video editing or 3D modeling. But, I do run a variety of graphically intense trading software and multiple monitors.
