I think naming the device the "3DS" is a bit of a hint as to what the console is about. I seriously doubt there will be the slightest bit of confusion in that department, even among those who aren't familiar with the product.
However, I don't think there's going to be a whole lot of consumer confusion over the difference between shopping for a 3D capable big screen HDTV and a little handheld console that plays 3D games on a 3.5" screen. Apples and oranges.
Anyone who actually uses a 3DS and sees how the 3D effect is limited to a narrow viewing angle, won't have to be terribly savvy to realize that a large version of the display used by the 3DS simply wouldn't be viewable in 3D by anyone without a near perpendicular viewing angle.
