typing from the dock now. it's much faster than i thought i'd be. some apps like chrome will go full size. other apps, facebook and xda labs app...won't.
video plays nicely. did some youtube briefly, it goes full screen nicely. my doorbell plays thru just fine in it's own window.
vudu app won't let me play HD...only sd. it also won't let me resize to full screen. the vudu website won't even allow me to play more than a trailer.
I was surprised to see "dex optimized" apps available. I didn't try any of them though.
I think overall with the 15min i've played with this it'd probably make a good travel setup. dock, bluetooth devices, and an hdmi cable. use a tv, or small portable monitor(i got a 13" portable for $129 on amazon)
One negative is I couldn't dock the phone with a case on it
