The 890 came out but that is around $400. I would guess they are, I have one and had a bad button after a few months. I had no issue at all getting a new one (they didn't even ask for a credit card to secure it). In fact I did not have to prove where/when I bought it (of course it only came out recently so it is not possible to have one that is not covered by warranty I don't think).
I have found the charging base could use an adjustment (it doesn't always sit right (meaning doesnt always start charging)).
Could just be great customer service (on the exchange, rather than them knowing of an issue affecting first gen units), but usually they want to close out existing stock in preparation for a new model (for the rebate).
I am going to bet on the '885' coming out soon.
I am trying to get to the point of using a touch screen tablet or the like, but that will cost much more than this, and take much more effort than one of these.
My wife loved it though, if that helps...
