Samsung Nexus S compare (T-Mobile)

The Samsung Nexus S gets points for its slick design, satisfying performance, and authentic Android user interface. But outside of the new Gingerbread OS and a faster processor, it doesn't offer as many new features as we had hoped.

A few quibbles notwithstanding, the powerhouse HTC One is a beautifully crafted, near-ideal smartphone.

The Samsung Nexus S brings a much-needed stock Android OS, Gingerbread, to AT&T. But eight months after its original debut, the handset feels underpowered and behind the smartphone curve.

It doesn't have all the features we'd like, but the Nexus One greatly enhances the Google Android family with a fast processor, good call quality, and improved voice control features. What's more, we love that all versions of the phone will be unlocked.

While the LG Nexus 4 wins on internal performance and user experience, anyone shopping for an unlocked phone should consider a comparable LTE handset first.
