Where've all the portable video players gone?

About half a year ago, when Gates just launched the "Windows portable media stations", hard disk based portable video players were all the rage, with all tech news prodicting it as "the next iPod".

Well, what do we see now? Portable video players are no where to be seen on the news or fourms, already pretty hard to find in stores, and I've never seen one used on the streets. Instead, people are saying that PSPs are great video players and memory sticks are selling like hot cakes. I don't know if people really do watch movies on their PSPs, but I guess sony accidently killed the portable video player market. Sometimes a product is going to die, no matter how the press likes it.

Say, where's the smart phones that they said were so cool? So far I only see ocassionaly, Treos and the Sony Ericsson P series. Where's the others? Shouldn't they be taking the world by storm?
