Google's followup to the Nexus One, the Nexus S is manufactured by Samsung and uses the Android 2.3 “Gingerbread” operating system, a 1 GHz Hummingbird processor and features a high-end AMOLED 400 x 800 resolution screen. It retails for around $529.99 or $99.99 with a 2-year T-Mobile contract.
"If you are an iPhone user this isn’t going to make you switch. If you’re an Android user you will want this phone more than any other. If you’re currently neither, we recommend that you go with the Nexus S. It is better than the iPhone in most ways."
"It seems like every couple of weeks we're saying something along the lines of "x is the best Android smartphone on the market right now." We'd like to tell you differently when it comes to the Nexus S, but the truth is, it really is the best Android device available right now."
"Overall, the Google Nexus S feels like a step backward for the Nexus line of 'Google phones,' and not just because of Google’s less ambitious agenda with the product. The Nexus S just doesn’t offer enough important hardware upgrades from the Nexus One to make up for the lower build quality.
