I am returning my SMP2 after using it for a couple weeks and going back to my AT2 and PS3. Let me tell you why...
The user interface is beyond annoying. It's slow, juttery, and unresponsive. It's nice to have 300 channels, if that's your thing, but if it's not, I'd sure like to just be able to scroll my favorites. Oh, I can add them to my favorites, but it's still a few clicks away and not at all a convenient feature. I have a sony tv and would love it if it added the channel to my favorites on my tv.
Netflix and Hulu are the main apps I will be using and Vudu occasionally. I'll admit, streaming looks great on netflix, and fine on hulu, but the experience is lost. Finding movies on netflix is a distracting experience and you can barely see the movie icons on the screen. It's so cluttered with unessential flotsam that it is not at all fun to just browse the movies. The movies are ordered by genre (as one would expect) but no sub-genre and no way to view an actor or directors filmography, another minus in my book. The search feature is broken. The on-screen keyboard is literally lifted off of a cell phone interface and would be more intuitive if you had an app to use instead of the controller. Alas, there is an app, but is wonky with the SMP2. The controller is ok, but the essential color coded buttons are annoying in a dark living room as you cannot even read the name of the color requiring you to turn on a light.
The DLNA is fantastic however. Streamed and played via usb stick every show or movie I "acquired" from the internet. Rome and Sopranos looked and played absolutely flawlessly. This alone being the one stand-out feature for the SMP2.
Music unlimited. If you have spotify and/or were interested in dabbling into sony's music subscription service, this device will frustrate you to no end. I launched the app and even uploaded some of my own music. It was slow to recognize my music, it's gracenote function destroyed all my metadata so all my uploaded music was scattered willy nilly into genres and artists. Ok, not the end of the world. When you play it however, it is very slow to respond and you can't even play the previous song, only the next song. How unintuitive is that?
Sony's PS3 Netflix and Hulu apps are about the best in the biz, I just don't like using my (aging) PS3 for anything but gaming. It blows my mind that they could provide such a underwhelming piece of hardware KNOWING that they could be offering so much more.
The HDMI sync feature was also wonky. I'd be playing a game on my PS3, and would suddenly switch inputs to the SMP2 input and back again. I would turn off my SMP2 only to have it turn back on as well as my TV five minutes later.
Me and my girlfriend really wanted to like this. I love my sony TV, my PS3, my sony vaio, etc.... But this? This SMP2 just fell short in every conceivable category. It's OK in everything it does but that's hardly going to cut it and definitely not going to find it's way into my living room.
EDIT: Amazon Streaming - Amazon streaming worked fine. I actually liked that I could watch some asian movies that weren't re-dubbed. The PQ was ok, but again, the U/I for Amazon was lacking. It seemed that all the movies were just dumped in a browsing screen and it was up to you to dig the one you wanted out. Amazon + Hulu + Netflix + Vudu? How did Sony get it so wrong? My 2 cents.....
