It wasn't very clear why Google was getting into the business of selling smartphone hardware until we saw that the Nexus One would be available for the four major US carriers, even if some options were fully unsubsidized. This wasn't even that unique though as RIM and Microsoft have had the same device across all carriers in the past too. I recently wrote why I thought the HTD Droid Incredible was the best new smartphone on Verizon Wireless and if you were having a tough time figuring out if you were going to buy the Google Nexus One or HTC Droid Incredible it looks like there will no longer be a choice to make.
For Verizon's network, you can buy the Droid Incredible by HTC, a powerful Android phone and similarly feature-packed cousin of the Nexus One.
Google also posted a blog entry recommending you buy the HTC Droid Incredible, but did not specifically state that the Nexus One is not going to come out with for Verizon. The post just states you should get an Incredible if you have been waiting for a Nexus One. It makes sense to me that they drop plans for the Verizon Nexus One since the Droid Incredible is a better device than the Nexus One in many respects and can be purchased for just $199.99 with a 2-year contract.
At this time you can buy a T-Mobile or AT&T version of the Google Nexus One, the Verizon one looks like it may have been dropped, and there is still no word on a Sprint version. Sprint and Verizon use the same wireless technology so I don't know why Google can't release a vanilla CDMA version that would allow the buyer to use with either Sprint or Verizon. With the Sprint HTC EVO 4G coming out very soon, I wonder if it will trump the Sprint Nexus One as well.
