I got my display dock. And it's pretty cool no doubt, but what really annoys me is that the phone must stay on while using continuum. I can't turn off the screen as the continuum stops working, even though it's acting as nothing more than a touch pad. For me, the biggest gripe is that it's an amoled screen and I want to avoid burn in as much as possible. Sitting for a long time on continuum is likely not helping the situation. I'm definitely going to be sending some feedback regarding that.
Other than that it is cool no doubt but I prefer my desktop. I just connected the dock to my tv and it works best there. The only weird part is when I connect it to my TV it asks if I would like "wired or wireless". And it says under wireless "connect dock to tv and then connect wirelessly". But then when I do that the phone searches and doesn't find a device to connect to. Not sure how that works. My guess is the dock is supposed to work as a miracast receiver as well.
Also a lot of apps/games that were claimed to be universal are not universal at all. This includes the weather channel, candy crush games, trivia crack. I think they are universal windows 8.1 games possibly.
Some apps are genuine like appraisin, baconit, readit, etc.. So it's pretty neat using all those. Nice to text with a keyboard too. But yah until we get a lot of universal apps it's just not really worth connecting it unless you're writing some word documents on the go or want to watch some movies while still using your phone and what not.
