I have had many streaming devices, I still have a vudu box that I bought it when they first came
out, I have a Roku player, My bd player LG BD590 250GB HD ,used to own a GOOGLE TV ,used to own a apple tv the one that comes with hard drive,I have a Xbox 360 slim that also stream, I had been using netflix since they start streaming, also hulu,amazon from my own experienced with streaming for years ,I will never stop buying blue rays, I have a collection of over 100 blue rays movies I own only 1 movie on my vudu account is avatar I did a comparison between my avatar blue ray movie and the one on my vudu account and I can tell the difference in quality between the bd and the hdx , I have a real good internet speed, how ever I can said that dvd could died because streaming dvd picture quality right now is far better quality than dvd ,But they are still behind when it comes to blue ray quality .When I want to watch a movie with a lot of special effects like tron ,avatar and movies that have pretty high bit rate I go and grab the blue ray ether renting or buying.I can tell the difference in picture quality on hdx vs bd movies maybe not in sound but picture quality there is a difference.
like i said before ,streaming will be always be behind blue ray.
There are so many problems that involve streaming, You do the list.
