I read a lot of books on my Kindle, and I've even gone down the route of publishing a few self-published books. You are absolutely right when it comes to self-published books, they are not as polished as the professionally published ones. It can be jarring to read a book and have a million grammatical and spelling errors. However, you have to realize that my investment in self-published books is significantly lower. They are usually much cheaper, they are updated (I think) more frequently, and they get the job done. Frankly, I like having both options around!
