The big difference between streaming and blu-ray for me is the audio. There are slight differences in the picture and you can find comparison pictures of 720 vs 1080 all over the web. Streaming doesn't seem to allow the pass thru of DTS. I have a decent sound system and not having the ability to use HD sound (Dolby TrueHD or DTS-MA) is a big flaw for me. I have 2 TV and the ability to stream is very convenient, but I keep my blu-rays handy for when I want the best sound I can get.
