No. I haven't had a problem with any of the books I have purchased for 4e. In fact, I would say that 4e books are, overall, some of the most consistently well done RPG books I've ever purchased. It is very nice of WotC to release lots of errata for free in an attempt to improve the game for their customers, but the published books create a perfectly fine game as written.
I agree. In fact, just ignore the errata - it'll save a lot of time and paper (and potential frustration!)
