Probably true, but it's not like "Google TV Streamer" is any better.
"Chromecast" was more puzzling. What's "Chrome"? Isn't that a browser? What does this have to do with anything? And what is "cast"? Does it broadcast something? Etc.
It'd be like if Apple decided to rebrand Macbook to be "Apple Laptop". Sure, it's accurate. It's also crap.
I think they gave out one from Logitech (with a keyboard!) at an I/O one year.
You get used to it. They also called the Apple smartwatch "Apple Watch" from the beginning, and nobody is complaining. So "Apple Laptop" or "Apple Phone" would be just as good.
The only market who wouldn't know is the same crowd that would never use a smart TV anyway.
