Everyone I know that has it uses it for note taking, pdf reading and drawing simple diagrams. Unless you're buying it do draw art I wouldn't buy it based on it's merit of drawing art.
To be fair DRM is a waste of opportunity. If I buy a book, movie, or album I want to use it however I choose as long as it doesn't breach copyright laws.
I've been burned too many times by DRM'd content that stops working after a service/app update, is useless when the company goes out of business, or when it works on one of my devices but not another.
