Artist who do art as a hobby? I don't see any serious artist going to use an iPad for their business. iPads like most tablets are just toys for most people.
Sure it can be used for business purposes. With the wealth of art apps available, and the quality of the stylus, it can quite easily replace a Wacom tablet, which is the industry standard today.
Still an ipad and can do many other things.... Lol not sure if I follow.
What I mean is, Wacom tablets are pretty much strictly used for their art applications, and don't have much of a purpose outside of that. With the iPad you can take it on a plane to watch movies, read books, browse the web, play games etc.
No one expects the Inquisition.
