Excellent device that has become an extremely useful part of my work and play life.
Whatever you want to do with a tablet, you can likely do with the iPad if you explore enough apps and figure out what you want.
Im a novelist and I work in law, and I use the iPad as a "red lining" tool with either iAnnotatePDF or Adobe Reader. This makes my editing process light-years more efficient than it was when I printed out pages and used an ink-pen.
Very quick, feels very polished. Everything always runs smoothly, as compared to my old iPad 2, which was getting quite chunky with the iOS 7 upgrade. Im an avid Ever note user.
