Confidence is good, but it can be taken too far? Roger McNamee from Elevation Partners (which has paid $425 million for a 39 percent stake in Palm) seems to think that the upcoming Palm (NSDQ: PALM) Pre is not only an iPhone killer, it will squash it like a bug. "You know the beautiful thing: June 29, 2009, is the two- year anniversary of the first shipment of the iPhone?Not one of those people will still be using an iPhone a month later" McNamee told Bloomberg. "Think about it?If you bought the first iPhone, you bought it because you wanted the coolest product on the market?Your two-year contract has just expired. Look around. Tell me what they're going to buy."
