NEW YORK (TheStreet) -- The recipe for any good tech show is five parts fantasy to one part reality. And sometimes, as we saw with a few shops at this year's CTIA mobile trade show in Orlando, that last part is optional.
There's nothing wrong with spinning fanciful tales about promising new tech opportunities; in fact, that's what these annual showcases are for. But in the rush to build big dreams, some ideas come untethered from actual consumer demand or nagging details like the existence of actual products.
Here are some of the biggest hype balloons: Mobile cloud,Cisco's(CSCO) Mobile Videoscape and 3D. All of these floated inside CTIA's conference and may not survive the sharp glare of sunlight outside the convention center.
