As promised, the Google Nexus S surfaced at Best Buy today. The store opened both physically and online at 8am EST and began selling an unlocked and locked version of the Nexus S. If you're not familiar with the Nexus S, it's the first Android phone to ship with both NFC and Android 2.3 (Gingerbread). As for its other specs, it sports a 4-inch Super-AMOLED display, 1 GHz Hummingbird processor, 5-megapixel camera, and a front-facing camera. The Nexus S is currently selling for $529.99 unlocked, or for $199.99 with a two-year T-Mobile service contract.
If you're looking for the latest Android device, it's not a bad purchase, but as Matt Miller previously mentioned, there are better spec'd devices on the market, that even take advantage of T-Mobile's HSPA+ network.
The other day I fired up my Nexus One. I have to admit that even though I love my HTC EVO and the HTC-ized Android experience, after having played again, it's clear that Google's out-of-box Android is pretty solid. So, you really can't go wrong with picking one up, not to mention that Google usually upgrades its own devices first.
