I'm thinking about buying a tablet to simplify my life on the jobsite. I want to be able to access all my drawing files (in VW format or pdf) via the tablet, but also be able to make written notes on the tablet either freehand or with a text tool. The four things I need most at the job are my drawings (with the ability to take notes), a calculator (shooting grades), and a camera. Is anyone else using a tablet this way? Is anyone using the Nomad App right now? Some feedback would be much appreciated.
