Regarding the 15" version, I have the 15" 256 GB Intel Graphics 2015 Model and I really, really, was expecting the same unit with the Skylake processor version of the quad core with the Intel graphics that has the on-board graphics RAM. I was hoping it would be lighter weight and longer battery life. Instead we have the discrete GPUs that undoubtedly will need more battery life than the Intel internal GPU.
