Most interesting is this:
Leaks suggest the Nexus One will be a global-system device with a 3.7-inch touch screen, five-megapixel camera, Wi-Fi connectivity, an accelerometer and a compass, according to CNN.com partner, Wired magazine. It is expected to run the latest version of the Android operating system, Android 2.1, which is also made by Google but runs on other phones as well.
It's widely speculated that the phone will be "unlocked," meaning users won't have to sign up for long-term contracts with a particular mobile carrier to use the phones -- as is the case with most major phones now.
This is a bigger advantage then I think people realize. Being able to buy without being linked t a contract or a particular carrier is a HUGE advantage I can't think of another phone sharing. If Google's goal is to quickly up their application base, I also have to acknowledge their open-platform method could make the Nexus/Android development a rapid fire world.
