I have met zero other DeX users, but know a ton of people with devices that support it. I currently have two extra docks and have offered to set up friends with a DeX setup ... they don't want a computer or understand how their phone and a TV and keyboard become one.

So I don't know if this will eat anyone's lunch, because I thought DeX would have proven the market if it existed.

And I don't think they'll touch Apple's marketshare with iPad because Android on tablets has been treated so badly for so long the market is uneasy

For now I'm kind of neutral leaning negative on this initiative. I fear more dumbed down, locked down and centrally controlled computing on PCs.

Both Google and Apple look very much like Microsoft with nothing new to offer: security - fail, UX - at the level of Windows 1.0, Multitasking - at the level of MS-DOS.
