Does anyone have any experience or knowledge of using ArcGIS 10.1 on a Dell XPS model laptop? If so, is this a good platform, or are there any particular issues. The Dell 15 comes with a Nvidia GeForce GT 640M / Intel HD 4000 graphics card. The RAM available seems fine at 8GB, 1,333MHz DDR3. I plan to use it for 3D Analyst and ArcPy scripting.
