Are any of them getting a major advertising push from anyone?

Because if they don't get it, they will sell a fraction of what the iPhone does.

Ask Creative Zen and iRiver about that. These and other manufacturers had better specs. than iPods for years and their sales went nowhere.

There were enthusiastic geeks, who only read spec. sheets or who just wanted to avoid iPods for whatever reason, but there were not enough of such customers to provide any real competition.

LG, Meizu and the rest better be prepared to spend several hundred million on a marketing campaign because that is what AT&T and Apple will do.

And if they do spend enough to get a lot of people (more than just gadgetphiles) looking for their products, they better deliver a user experience that appeals to the mass market, meaning easy and intuitive as well as flashy.

Microsoft can't wait to revise their mobile OS to offer a comparable experience as long as they did to come out with the Zune. And when they did, it wasn't better and they tried sort of to copy the click wheel.
