iPhone Killer
The iPhone is made by one manufacturer, controlled as far as applications (one source- Apple), and only available on one network. When Google brings the Nexus one and Dell brings their Android phone to AT&T, those who sat on the fence about the iPhone due to it's lack of support for flash, user nonreplaceable battery, and other features, will flock to the Android phones. Also, since Android phones are being made available on Verizon as well as T-Mobile, not to mention the Palm Pre and Pixi being made available on Verizon, iPhone will find itself surrounded by the Android platform (as well as other Linux Platforms). It's only a matter of time before Linux outsells iPhone.
