Laptops generally lack the raw power for seriously high-level computing, which is where portable workstations come into play. With powerful processors, plentiful storage and top-notch screens these devices don't come cheap, and are relatively rare. Lenovo's 15.6-inch ThinkPad P1 is certified for use with ArcGIS, AutoCAD, CATIA, Creo, Inventor, Microstation, NX, PDMS, Revit, Solid Edge, SolidWorks and Vectorworks.
