Whether you want to buy the kickstarter or not, that's up to you. It's a pricey collectors item, a beautiful piece of art, but the story is ultimately the same.
I love books, and I also love beautiful, sort of definitive editions. It's a weird mindset I have, but there you go! I have every leatherbound except for Warbreaker (which I will get when the next run is released). I do use them for reading. Personally, I think it adds to the experience. The art, the font, the look, the quality...it all adds to my experience reading the story. I don't go anywhere with these leatherbounds, I read them in the comfort of my own home, and I read them in a way where I won't damage them. I'll admit, I typically read all of my books as if they were a leatherbound haha. However, I mostly read on my bed, I don't usually handle the book much, and I don't really read in chairs, unless it's for school or work. They are still in excellent quality! Beyond reading them, they are beautiful display pieces! I look at them and I feel good about my purchases! Cannot wait for The Way of Kings!
