Too much smoke
The home computer brought computing into the home and allowed Joe Public access to a plenitude of possibilities.
The portable computer made it "portable", Joe Public could now take his plenitude of possibilities anywhere with him.
The portable telephone meant he could also communicate verbally whilst on the move.
The smartphone meant he could communicate and use his plenitude of possibilities whilst on the move.
The wearables: Difficult to relate them to anything other than fashion accessories or minor appendages to existing hardware. They won't actually give Joe Public anything more than he already has.
Personally I see this as a quick fad UNLESS one of them is capable of producing an interactive holographic image/screen/interface which has 7 day autonomy.
Gartner as usual are a "little overly" optimistic, they must be smoking crack again..... Cisco appear to be smoking on a very little light weed , good for Cisco.
Interesting article all the same
