I use my SP4 Core i5 8 GB RAM 256 GB for scientific research, drawing, 3D modelling, and some limited coding which means that I mostly use Office 2013, Adobe Creative Suite 5, Origin Labs curve fitting software, PyMol protein 3D structure visualization software, OneNote, Blender, Autodesk SketchBook, and Microsoft Visual Studio 2015 Community. They all work fine except for Photoshop CS5 which has buggy stylus support (even with Wacom tablets of which I have the Intuos Pro Medium). An SP4 will eat Office 365 like it's nothing.
