Chromecasts are my go-to Christmas gifts every year.
Why can't I buy something to just stream my screen? Like the steam link but for everything. Not just steam.
I buy box sets from Amazon Video and watch them (which has to be laptop). My girlfriend watches a lot of BBC iPlayer, we both watch Netflix. On occasion I'll download something and it'll happily stream from my phone (Localcast) or laptop (Videostream).
