Definitely a case where mileage varies for people. I'm on 2.0.0 on a Touch. And it doesn't bug me. I mostly read library books on it... sideloaded epubs through Adobe. And they work fine for me. (Emphasis on the "for me" part.)
2.1.4 (or .6, or whatever) will come out whenever it comes out. In the meantime, I've got books to read. (Nothing like a three week lending period to give you some incentive.
)
