Both sizes of the Wacom MobileStudio Pro are heavyweight devices – literally and figuratively. No one is going to mistake even the smaller model for an iPad Pro – it is chunky and too heavy to hold in one hand for an extended period of time. But to do so would be to utterly miss the point of the MSP – as the bold, confident name suggests, it is a mobile studio; a portable workstation in tablet form. Both versions we tried were full-fat Intel Core i7 models, with 16GB of RAM onboard and an Intel Iris Graphics 550 GPU in the case of the HD-screened 13-inch, and a scarcely believable NVIDIA Quadro M1000M graphics card with 4GB GDDR5 VRAM and a 4K ultra HD screen in the 16-inch MobileStudio Pro. That is SERIOUS power.
