Please don't disown me! I'm new..

Hi geeks and geekesses. I know a little about stuff but not what I need.

I would like to get my mother some Internet tech and I have seen a Amazon HDX for £80 new, for Xmas of course. She likes reading, would love eBay to herself and the 50" is not yet Smart.

So my question is if I buy the HDX and get Google Apps n stuff on it will it work a Chromecast?

The £80 HDX ends tomorrow at Argos so much input would be much appreciated.

Thx reconminicon.
