Performance, the thing about basic kindle (not talking about Fires) is they are for reading, they perform fast enough for you to read on, faster than you can individually turn a page on a paperback. They dont need to be faster.
If you want a device that is going to let you carry around hundreds of books without the bulk, make it easy to hilight and review the nuggets of information in a book and review, make it so you read more because its an enjoyable experience, you can sample new books for free that otherwise you might not have checked out. Then hell yes its worth it. Shit I'd have paid hundreds for mine. However if you read three books a year - dont bother.
