I got the newer model and it's quite good.
I have a 3 year old LG 42LD550, which I bought with the older style 'Netcast'. Seems to me pretty much useless. The Youtube app does not appear to work any longer (and I saw other posts on that). I'm trying to resurrect the use of this wireless device that I spent maybe $100 on to see if I could conceivably use to stream Amazon Prime, but seems like only the original 'apps' (for lack of a better word) appear. Does anyone have a comment or advice ?
