Well it looks like you can't buy it ( Chromecast )in Canada yet according to our BestBuy and Future Shops. But I might be able to get it through Amazon if they will ship it to me. I think this unit will work best for me as all I want is the image I am seeing on my PC.

I have chromecast, and I like it. I don't think it will do what you are wanting though. Basically, you use a smart phone like a remote to the chromecast. For example: If you have a netflix app on your phone, you start watching on your phone, then press an icon that makes it go to chromecast. At that point you can use your phone to pause, rewind, fast forward, or select scenes. Everything shows on the TV. But once you start watching on the TV, you can use your phone normally to make calls, or even play games while the chromecast does it's thing. In other words, it doesn't stream to your phone, and then to chromecast. Your phone just provides the interface. The show streams from your home wi-fi directly to chromecast.
I hope that helps.
EDIT: After reading Penman 1's experience, I guess you can go directly from your computer. I've never tried this part though. All I've ever used was my iphone.
