I've had an iPad for about three years. It appeared to be the magical way forward for technology. As a musician, I regularly use it to display scores, and really like it for this.
Otherwise, I hardly use it at all. I don't like reading on it. I don't like browsing the web on it. I don't like playing games on it. I don't like typing on it. For almost everything I've tried to do with it, either a regular desktop/laptop computer or a phone seems more pleasant for me.
But I do see plenty of other people using them constantly for things which I do not; your experience may vary.
You might try to identify a few specific applications that might serve your purpose, and see if you can try them out on someone else's tablet. Even if you (like me) don't like a tablet for most things, if it works well for a specific purpose or two, it may still be worth having.
