Hi all. I looked, but could not find an answer pertaining to this. Why buy a Chromecast when I can connect my Sony Vaio Duo 11 Ultrabook directly to my receiver via HDMI? It seems to me that connecting my laptop does everything the Chromecast does, but more. Am I missing something? Please, professionals, shed some light on what I am missing. (besides the size difference) Thanks!!
Size difference, convenience...that's really all it is. I mean, if you wanted to stream something on Netflix, for example, it's theoretically easier to just pick up your phone, pull up the movie/show to watch and send it to the Chromecast vs. booting up your laptop and plugging in the cable. What if you have to use the computer for some other purpose, but your wife/gf/so/roommate/etc wants to watch something on Netflix? In that case the Chromecast would come in handy.
The only other thing I can think of that my friends and I like to with the Chromecast when we're hanging out is that with YouTube you can pull it up and then anyone can add videos to the current playlist right from their phone (assuming they're on the same wifi network), so in that respect it's kind of cool for parties and such.
I guess the real answer to your question is that it's a $35 dollar device that can save you the time and hassle of having to wire up your computer each time you want to stream something.
