Actually, Samsung and LG killed the trade show star. They're so hell bent on one-upping each other, they barely dream of something before shoveling it into the marketplace. C'mon, two Note 4's?
So anyway, these trade shows are little more than a bunch of products they're not going to manufacture, plus a few products that they are. But none of them are new, cuz you've already read about them, long ago, probably right here on Slashdot.
