NEW YORK (TheStreet) -- The transitive property of . . . smartphones?Just because Apple ( AAPL), Microsoft ( MSFT) and Nokia ( NOK) are purportedly releasing smartphones after Labor Day weekend, does it automatically stand to reason that Amazon ( AMZN) will too? According to some in the media -- including Marketwatch -- the answer is "yes." But that answer relies upon the transitive property of smartphones, which we'll explain in a moment, and not on single sources (reliable or not) or any other shred of hard evidence. Here's how the party started: Amazon sent out invitations Thursday about a Sept. 6 event. They didn't say what it was about. The best guess -- because they already have a tablet and the meeting seems to be organized by Amazon's Kindle division -- is that they will announce the next version of their Kindle. But even that, which makes the most intuitive sense, is pure guesswork and should be clearly stamped with a speculative label. Reuters did well in this regard right in their headline: "Amazon event on September 6 sparks Kindle speculation." Some in the media, though, went in an entirely different direction. Problem is, their reasoning was reed-thin, their sourcing nonexistent and, worst of all, they didn't, like the Marketwatch story on their more reasonable prospect of a Kindle, come with a disclaimer attached: This is unadulterated speculation. Here's Marketwatch's headline: "Will Amazon launch smartphone in September?" Their justification introduced us to that transitive property of smartphones: if A and B is doing it, then so will C.
With Amazon's AMZN -0.05% event timed for Sept. 6, one day after a Microsoft Corp. MSFT -0.93% holds a press conference in conjunction with Nokia Corp. NOK -4.69% in New York, and one week before Apple Inc. AAPL -0.11% is expected to introduce the iPhone 5, it's entirely feasible that Amazon could also talk about or launch its much-anticipated smartphone.An "entirely feasible" concept, unsupported by an ounce of evidence, only serves to add to a culture of fervid speculation and does not merit an article, much less one that comes without a warning label.
