We gotta start with John Dvorak, who cut straight to the point and said "The Google phone is doomed." Additional money quotes include "Google is actually not a charismatic company that can make this new platform happen in a big way," and "When I see a bunch of joiners jumping on some unknown, unreleased unfinished pipe dream, I actually laugh." He even roped in the iPhone, calling it more of a "photo album than a phone." Actually, Dvorak's whole column is a great read even if just to experience the man's naked anger towards every phone ever made.
Not to be outdone at the contrarian game, Microsoft CEO Steve Ballmer came out swinging as well, saying "Their efforts are just some words on paper right now." Actually, he does have a point there -- although Google and HTC may have been developing that "Dream" prototype, the real news will come in late 2008 when Android devices start shipping. How does that compare to WinMo, Steve? "They have a press release, we have many, many millions of customers, great software, many hardware devices and they're welcome in our world."
