On Jan. 22 I received my Nexus One directly from Google.
Since I lived in Hong Kong I bought the USD529.00 fully unlocked version.
The purchasing experience at Google’s Nexus One web site was very present. Google recognized I already had a credit card in my Google Checkout account, and auto filled the shipping address for my order. After choosing the unlocked version of the Nexus One, it automatically chose an AC adpater suitable for Hong Kong. I guess that’s because of the shipping address. I excluded it as I believe it is more convenient to charge via USB.
Within 24 hours I received a message from Google stating that my order had shipped. For international orders Google use DHL as the carrier.
