First of all it's possible to get an Ethernet adaptor for the Chromecast if you really need to go down that route. Second everyone always misses my absolute favourite feature of the Chromecast which is that it it doesn't have apps that require you to login (by the way El Reg, Google doesn't host the receiver apps - the app developers host them on their own servers). The benefit of not having apps that need to be logged in to - means for example - a friend might rent a movie on Google Play (or in fact they might have bought the movie) and can come to your house, hit cast (they don't even need to be connected to your WiFi if you have enabled guest mode on the Chromecast) and you can be watching a movie that you don't own. The same goes for things like Netflix you personally don't have to subscribe but someone can come to your house who does subscribe and send Netflix straight to the Chromecast, no-one ever has to bother logging in and therefore don't have to remember to log out when they leave.
