Hello, I am interested in the Surface Pro 4 and at the same time I am waiting for a new Mac laptop. Right now, I only have an old MBP 17" 2010 (i7 2.66GHz, 8GB, Toshiba 500GB HD, Intel HD Graphics and Nvidia GeForce GT 330M with 512MB). In terms of overall performance and 3D graphics performance, how is the i5/i7 SP4 compared with the MBP 17" mid 2010 if the latter has a HD or SSD? I know that it is good to upgrade the HD of my MBP 17" to SSD. If I do, I will buy the 1TB version. Given the cost, I wonder if I should just buy a SP4 instead. I am less interested in the Surface Book even it has a GPU because: 1. It is heavier than the SP4. 2. When the screen is separated, the battery life is about an hour.
