David Pogue at the NY Times just published an interesting review of the recently launched Sprint Nextel Over-the-Air music download service.

He likes the idea of the Over-The-Air Music Download service. He thinks though that Sprint's pricing is too high ($2.50/song), the music catalog is too small and that users cannot use the downloaded music files as ring-tones sucks big time.
Additionally, I think that the Samsung SPH-A940 (photo) and the Sanyo MM-9000 are not really exciting mobile phones, but you need one of those to enjoy Sprint's new Power Vision service. See also this early review of the Sprint Nextel music service.
