I still think smart phones that dock and become full PC work stations would be great.
Sharing data/settings already works great with the cloud.
You still get the same bulk as carrying around PC+phone.
The only reason is that maybe it's a bit cheaper because you use the same CPU for both, but the drawbacks (not being able to use both at the same time, slower proc for the PC) don't make it worth.
Local wired (or Bluetooth) data transmission will beat the Cloud on performance, not rely on third party security, and be immune from interruptions.
I see strong potential for movement away from the cloud.
The HP Elite x3 phone already does that.
