I'm looking forward to change my Mac Book Pro Retina 13" and I'm sincere, Macbook is that light and portable, other than having Retina resolution, it makes me thinking about it. Maximum portability and when I need it, chance of connecting an external monitor. Only question regards the performance matter. Would it be enough to make run a Parallels virtual machine plus Windows 8.1/10 + Visual Studio 2017? Projects are not that huge (solutions of 15-20 projects max) but I need to work flawlessly and keeping a good battery management. Any experience 'bout that? Thx in advance
