I just replaced a 2 year old Samsung Bluray that did pandora netflix. I thought it sucked. It was SLOW at startup, and wouldn't play many blurays even though it was updated firmware wise. The netflix interface really sucked, it was browse your queue only. no search, no suggestions, just your queue.
Replaced it with a Sony BDP-S185 Blu-Ray Disc Player
So far, it's been working REALLY well. all the standard online video sources. Netflix has a very good interface. and startup is very fast. I'm debating just replacing the other players in the house with additional units (an old Sony Bluray that has no internet content and a DVD player) with more. at only $78, it was a no brainer.
For other smart stuff, I have an older Roku, which is okay, but lack of an easy NAS browser sucks. A boxee that's pretty good, but netflix isn't as nice, and an internet TV that's nice, but slow at startup.
The BDP-S185 impresses me the most 'cause it was so cheap and does such a good job. It's also TINY! one of the smallest blurays I've found. (huge compared to a ruku though. about the size of a DVD player)
