If you’re using a tablet, you’re not going to be a power user and push a tablet to its limits. The most you can do with a tablet is watch a movie or do some internet surfing.
Not true. I'm writing two novels, and multiple short stories on my iPads, have designed two house remodels, and three kitchen remodels all of the iPad in 3D for my rental properties. I've designed jewelry on my iPad for myself and my girlfriend that was ultimately made by our jeweler. Now with the new Apple Pencil, that kind of remodel and design work will be a lot easier. You really don't know what you can do until you actually work with one.
