Samsung Nexus S was just made available hours ago by Best Buy, either unlocked for $529.99, or for $199.99 with a T-Mobile commitment. This is the first Android 2.3 handset available on the market and don’t expect any Samsung UI customization on it, as it’s free of such software burden.

This is a 4 inch smartphone, with a 1GHz CPU, 5MP camera and the rest of the usual specs, especially as far as connectivity is concerned. A major plus is the NFC support, that will help you make wireless payments in the future and use the device for ticketing and shopping. Will you buy a Nexus S now or wait for the first dual core smartphones of 2011?
