Sony is exiting the PDA market in both the US and Europe, it seems. There original vision wasn't bad, it was simply too proprietary and couldn't keep up with non-proprietary solutions. On the handheld side, PDAs are not going to vanish anyway, they'll just be morph with Smartphones and devices of the sort (although I think there will always be a market, however small, for "pure" PDAs). Maybe Sony is planning on reviving some of the Clie stuff through its cellphone venture with Ericsson...
