This is the type of minutia that wears down men’s souls:

The structures of the trackball module and the Hall IC look almost the same as used in the BlackBerry Bold of Research In Motion Ltd.

Translated into English, or Common, this says that the trackball used in the G1 is the same as the one found in BlackBerrys. That’s according to one engineer, at least.

And what have we gained with this knowledge, that a small round piece of plastic found in one device is the same as small piece of plastic found on another device? ::shrugs shoulders::
