Google has released two phones ever, both of which are easily rootable.
Easily by the average /. reader - but I suspect that HTC would like to see that bar lowered significantly. I imagine that a hardware vendor (HTC, for example, but it could be anyone) wanting to put a serious hand-held device into an enterprise environment would like to make it simple to cut the umbilical chord to Google.
Or just to offer power users more options to rid themselves of the constant sucking noise of Google (and Facebook and Yelp and the rest of the bottom-feeders) eavesdropping on our every action, thought, movement.
This may be FUD, but there's a grain of truth in there somewhere!
