Picked up a chromecast yesterday.
It does what I bought it for well, and fits my needs exactly.
It doesnt do as much else as I thought it would, but I expect more apps will become cast aware in time.
I bought it to stream Plex to non smart tvs, and that works well, as does Iplayer (and Bt sport not that I use it)
It would be nice if a few more catch up services become cast aware, was also dissapointed that chome itself cannot be cast, except from a PC, not a show stopper, but thought it would be a nice to have.
Cleverly marketed to hide its limitations until you dig deeper.
Would I buy again? Honestly Id be tempted for a cheaper Now tv instead. But it does do what I want, anything else would have been a bonus, I also have some other uses lined up which nothing else would be so suitable for. May end up with another, (or now tv instead) if it works well for my other tasks once I try it out further
