If you make a lot of maps for your company, Pro has some great cartographic improvements upon arcmap:
- Text anti-aliasing and more dynamic graphic inputs make for appealing map products.
- Multiple layout functionality and the demise of those ridiculously slow dialog windows for everything from labeling and symbology to text and graphic input make for more streamlined production.
- The side-by 3D views are super cool, but without the hardware and network support capabilities, they will crash your system, and make you question the meaning of your cubicle-bound existence.
It's definitely got great capability, however I'm not yet seeing the intuitiveness, and speed, for which is being touted.
