Only had time for a quick go at it.
The keyboard input really sucks, horrible design, I am sure they will improve on this, I set my password to never ask for the appstore because it's such a pain.
Siri works pretty good from my brief try. I can say "play Sphere on Netflix" and it will load it up for me, "find movies from 2009 on Netflix" etc The problem I have with it though is I am using Getflix to watch Netflix in the U.S. but it seems like Siri might be searching Netflix from Australia (my region) which mean it doesn't work fantastically as the catalogues are pretty different.
Everything is nice and snappy.
No support for 24hz
, I haven't tried playing media files yet to see how they go.
Had a quick go of the free Rayman game, looked and ran great, controls were alright on the touchpad.
I like how it has HDMI-CEC, so when I turn it off it turns of my receiver and TV, nice touch.
