I moved to the Android world about 2 months ago with the Galaxy S8 and absolutely love it. I was previously using a Microsoft Lumia 950XL which had Continuum built in its Windows Mobile operating system. It's basically what Samsung Dex was inspired from so when I heard Samsung was working on it, I was very interested.
One thing that Continuum did that was amazing was that you could actually go into the desktop mode wirelessly on any Windows 10 laptop or Miracast capable device.
It would be awesome if Samsung Dex capable devices could do the same so that you don't have to dock the phone and can use the phone screen as a trackpad similar to Continuum.
