Should I Buy an iPad?

Updated: 11.15.13

On October 22nd, Apple will be announcing the release of several new products, including a souped-up iPad.
Up until now, I haven't bought an iPad. I own just about every other Apple product: a MacBook Pro, AppleTV, an iPhone, and a few iPods. I've noodled with my friends' iPads and have enjoyed the experience. It works basically like a big iPhone.
I've been resisting getting an iPad for several reasons. For one, I like to give my eyes a rest from the tyranny of screens. I don't like reading e-books, even though I recognize their inherent advantages over their physical counterparts (search, highlighting, etc.). Also, I like using the MacBook's physical keyboard and multi-touch touchpad.
Tablets are the way of the future.
Still, tablets are the way of the future. With a keyboard case, they function as de facto computers. I love the near-instant boot-up time. When I travel, I usually don't write too much. I'm content to consume content more than create it. I can't imagine writing a book on an iPad.
Do you own an iPad? Do you use it much? What do you like about it?
