@evildictaitor: I hate to say it, but DeathByVisualStudio does kind of have a point here. If the average consumer doesn't end up loving the device within 10 minutes of trying it out in a store, they probably won't buy it. And if they read the same websites that DBVS does, they'll come in with the same expectations.
It may not say much about the actual long-term usability of Windows RT, but it definitely does say something about its chances of succeeding commercially.
Let's not pretend that DBVS is an average consumer or that he went into that store to buy a Windows RT tablet. By the sounds of it, he went into the store to mock the staff's lack of knowledge of Windows RT.
Let's be honest. DBVS and WTWF weren't ever going to buy Windows RT tablets. But then you're probably not going to sell a steak to a vegetarian or a Ford car to the CEO of Toyota. That doesn't mean that the steak isn't juicy or that the Ford car isn't better. It's that when you're trying to sell something to someone who's already chosen not to want your product, you're not going to be able to convince them otherwise, no matter what you do.
