I guess from that viewpoint it's moderately interesting but as a phone it's really not much to get excited about compared to other modern Android phones like the Droid. Bah... I was expecting something huge!
The Droid is CDMA, which is a deal-killer for anyone travelling internationally. Also it's the first time in the US that a major phone has been sold with an option to buy it without a contract. This is fantastic from a user freedom perspective as Telco contracts in the US are typically quite abusive.
It seems another difference is that this time HTC is just a subcontractor, while Google really takes over marketing of N1.
