in a similar situation, not sure whether to get a roku lt or a chromecast
i really want the chromecast but its very limited at the moment. it doesnt let you stream local content, ie your own pictures, videos or and videos you may have downloaded onto your laptop. even music that you put into your google play it wont stream. has to be movies/music bought from the play store. because the android dongles have the micro sd slot, i can play films direct to my basic tv using it.
because of that, im edging toward the android stick. £36.99 or £48 with the wireless air keyboard
