how well does the ipad lightning to hdmi adapter work, and what are the video issues?Already did that. It's main purpose is collecting dust since i bought my Fire TV last year. It is neither really mobile, nor really useful my purpose, which is to connect my iPad to a hotel room TV. Due to the lack of a browser i can't login in most hotel wifi spots with it and peer to peer Airplay isn't available for this model (only for ATV3 produced after march 2013). So i am looking again at the adapter (despite its picture quality issues) for my next vacation.
I have an LG "smart" tv (otherwise a good tv, but the 'apps' are crap; what a ripoff with expiring apps! and the last system software update on the tv was in 2011) for which Amazon just discontinued support -- so I can't use it to watch Prime video directly anymore. It was a crappy app anyway, so I rarely used it. But there are times when I might want to - video is better on a 42" from my couch than a 27" at my desk or the 9.7" iPad!
Waiting to see whether the next ATV will be worth it - and I know it won't include access to prime. So, I'll compare to Roku once the ATV is announced in a few weeks. So, I may still need an alternate way to get prime video to my TV.
