I was kind of wondering what Chromecast is... I have a lot of ads about it but really don't know how good it is. I know that it is some sort of tv thing...???

I have seen it a lot on ebay, ads, and other sites. So is it good.

Also I was wondering if you have to log in to your tv provider to use it. Do you have to pay monthly?

How good is it, for those of you that have it?
I wonder if I should get it, is it similar to rabbit tv or other things that give you online tv.

Thanks,
