Apparently, the Centro can’t completely satisfy all the Palm users who currently use a Treo 680 - the boys at Amazon Germany seem to be among the first to figure this out.

Their newsletter mentions blow-out deals on a variety of cell phones - on page two, the Treo 680 can be found near the bottom.

While the price of about 450 Euros is outrageous (much more than the device cost when it first came out), I nevertheless felt like letting you know - Amazon wouldn’t run this if it didn’t move produce after all…
