Now that is good news.
An Android phone, sold without any non-SENSE to BLUR the experience would be just what Google needs right now.
That is a phone I would buy. Make it Apple and Windows-like by saying "hands off the phone", and people will buy it because they know what they're buying- and they don't need to hack the phone to get it to work the way they want.
The Nexus Two should be sold on the Google website, in partnership with the different carriers for your region that have decided to offer a subsidy on the 'Two. That way, Google can handle the warranties and support issues that come up just like the other makers do.
This has to be a phone that people want so that carriers will accept that they can't annoy their customers but still offer the subsidy.
That way, the phone will succed.
