I have the Sony and LOVE IT. I would recommend this player until the cows come home.
Its only real drawback is the lack of wireless (no you cant install a wifi USB...Sony says no, but I tried it anyway, doesnt work). If you can get around the wired only, its a fantastic player.
It supports way more streaming services than listed here. I cant recall them all, but off the top of my head there's, Netflix, Amazon, Hulu, YouTube, Vudu, Pandora, Slacker and at least 15 other services of various flavors.
