Summary: The good: This unit does well when it comes to playing discs, files from an attached hard drive, and even most of the streaming services. It streams YouTube, Hulu Plus, and others with no problems. The bad: This unit has big problems streaming Netflix. It stops, buffers, plays for a few seconds, stops again, etc. Pretty much any peak time you can't use it. While my BDP-S580 was choking up, I decided to load a Netflix stream on my computer and tablet.
Summary: Be aware that the firmware M07.R.0615 that your S580 may want you to upgrade to includes Cinavia, a water marking technology that restricts playback options on your player (Sony describes it as a benefit/improvement...for whom? Their pocketbooks perhaps).
Summary: This is a good Blu-ray Player. Along with the HDMI feature it gives excellent Picture and Sound. It's weakness is in the streaming/internet feature. Streaming netflix is not good. It keeps dropping the connection. I tried the wireless connection and it wouldn't connect. I have it wired in directly to my network now but it still drops the signal to often and sometime its difficult to reconnect. I have gone back to using my Wii for Netflix.
Wi-Fi Reception Makes this Un-usable at any Distance from Router

Summary: This is actually a very nice unit. The blu-ray picture was awesome. It is very quiet. Unfortunately I had to return it because of the weak Wi-Fi receiver that others have mentioned (if its the receiver or the antenna I do not know). I could only get 10% reception even through an Apple TV sitting right next to it always gets over 50% and a laptop right in front it gets over 60%. Because of the poor reception I could not stream Netflix (which works fine on the Apple TV).
Summary: My wife and I are addicted to Netflix streaming on our PS3 - so much so that we are considering getting rid of digital cable. I was considering getting a second PS3 but the price difference between it and other BR players (I don't play video games, really) is really quite large. The good: It has more bells and whistles than the PS3 as far as content. There are all kinds of other streaming video options available. It also starts and plays BR movies as fast as the PS3.
