Basically, I am looking at something that will be capable of rendering 3D models in programs like MasterCAM and SolidWorks design suite, but has a long enough battery life that it will be efficient for writing CNC programs on the go.
Requirements for MasterCAM and SolidWorks is a minimum 8 GB of memory, 16 is ideal. CPU must be 64 bit and support SSE2 but since that has been a standard since the P4, it shouldn't matter. Ideally a dedicated GPU with a minimum 2GB of memory. I don't know if there are Quadro based tablets, but that is the recommended video card series. Preferred 500 GB of storage on an SSD. Must have USB for mouse support and expandable storage like microSD is fine.
