Android phones, apps and tablets

Some smart TVs will act as Chromecast receivers.

Koush's AirCast was implementing Chromecast "transmitting". Google are trying pretty hard to kill this because AirCast doesn't need an app's cooperation, hence DRM crap... See http://www.droid-life.com/tag/allcast/

You probably need some kind of MHL Cable:

Unless you have a nexus 4, in which case SlimPort.

SlimPort it is, but following on from this, what would people get, Chromecast or just a cable? Wireless is nice, but the cable seems like much less hassle.
