Best Buy online lists the 350 (in stock) and 950 (as backordered) but still does not list the 650.
I wonder if they still have a bunch of the 600s left in stock and want to get rid of them first? That kind of makes sense since the 600 had a terrble screen to read from, they probably had trouble selling them or got a lot of returns.
Still it is odd that they list the 950 which still hasn't been released but don't list the 650 which has been released.
