Yeah, I take your point. However, in the rapidly evolving world of IT, the public need to think about things *before* they happen. Analysts play a role in this - even if they have as much insight and foresight as a Wired.com hack, because here we all are, offering argument and counter-argument.
The analysts don't have 20:20 crystal balls, but they usually do offer their reasoning. We obviously can't go by the predictions offered to us by any players in the game, such as Google, Samsung, MS, Apple etc because they want to bend our perception to their ends. The big players do, however, have their own analysts, and I suspect that some of them are very good at what they do, and have more expensively-gained information to study.
