Nexus One Dev Phone vs. a regular Nexus One Phone (retail version)

The specif开发者_如何学Pythonics of the Nexus One Dev Phone compared to a regular N1 Phone

I'd like to buy a N1 Dev Phone for dev purposes but also for ordinary everyday usage. So are there any specifics in the Dev Version of N1 I should care about? Is there anything that would inhibit a regular day to day usage and what are the differences to the regular retail version of the Phone?

Apart from:

• SIM unlocked - Put any SIM in the device
• Test out your apps on real hardware before publishing them to the world
• Ability to see copy protected Android Market apps

As far as i know, the Nexus One is only one Product, there isn't a special developer edition, with the only differences being vendor "lock-in" by some carriers, Vodafone comes to mind.

So the developer version would get you "bare metal" Android 2.2, which according to this link (http://android-developers.blogspot.com/2010/08/nexus-one-developer-phone.html) is standard Android 2.1, updated to 2.2 at first boot.
