Samsung Nexus S (Sprint)
This was Google's second run at making a phone to its specifications, only this time, Samsung is doing the manufacturing and Sprint (S) is selling it. Two years ago, HTC made the Nexus One and Google sold it online. But the retailing experiment failed, or at least was far less revolutionary than Google hoped.
The Nexus S runs on Google Android 2.3 Gingerbread operating system and works on Sprint's WiMax 4G service. The Nexus S includes some of Google's favorite projects, including NFC, which may one day allow phones to make purchases with a swipe at a sales counter.
The Nexus phones are big among Android fans who see them as more purely Android than other versions in the market. The Nexus S runs on Android 2.3 or Gingerbread, this is an advantage now, but it will soon be eclipsed by Android 3.0 or Ice Cream Sandwich (see above).
