I'd like to offer my thoughts to those who are interested...
These days I just dont have the time to hack around and I like things to work. Quickflix works. I've been starved of good streaming services since I moved back home from the UK. When Quickflix was released I signed up straight away to check it out.
I love the app integration on my Bravia. It works flawlessly for non PPV. So easy to start movies. I've had no problems with stuttering etc, so I conclude this is ISP or connection related where others have complained. Video quality is sufficient (think 700mb AVI) and some HD content is available.
The biggest complaint everyone agrees on is the content library is tiny at launch and is largely old. A quick look at quickflix.com.au shows you what we are missing out on. There is some current content on their PPV list but this can only be accessed via the web interface right now, not the Bravia integration. Its a pain busting the HDMI cable out and hooking the laptop up, call me lazy but thats why I bought an Internet TV.
Verdict so far - good platform, content needs improvement, PPV access needs to be added to the Bravia app. I will see how it goes for a couple of months, $10 - $17 a month is nothing really.
We don't currently have Sky where we are renting, but we will be getting it in a couple of months when we move into our new house we are building, so we may get rid of Quickflix then if the content hasn't started improving as promised, but I'm happy with it right now.
