Even if reading from a backlit screen doesn't bother you, you have to recognize that reading outside is much better on an e-ink display.
I have a Kindle and I like it because it's small, the battery lasts forever, it's single-purpose, its inexpensive, and is usable in all lighting conditions. Of course you can come up with an equivalent list for your tablet, but the reasons will be different and those differences are enough to justify both products existing.
