Is this an evolution of the smartphone or another iteration of the PC? The Apple II+ was often referred to as the Visicalc machine, since that single-use functionality was enough to launch the device category. Smartphones started out as telephones, but that is a smaller and smaller part of what they are becoming.
I've heard rumors that Sprint will be offering a Nokia phone for the first time. Not really a game changer, but interesting, since it seems that Sprint has been reluctant in the past to support Windows phones. Maybe this is changing with its new ownership.
I've also heard that Samsung may use Tizen for its smart watch.
It is natural that the netwrok operators are now looking elsewhere to increase their revenues.
Smartphones are commodity now , whereas provinding connectivity solutions to cars and wearbale devices can be a premium revenue generating opportunity at least for a few coming years.
Regarding the feature phones still making the large portion of the pie , I think the smartphones are mainly bought by the young generation and the business community whereas the rest of the population is still embracing the simple to use no-nonsense feature phones.
I compare this with motocycle vs scooter trend - while the young male generation has switched over the motorbikes the remaining population is hooked to those scooters and scooterates.
I think MWC 2014 could trigger some fundamental changes in Mobile World Congress. While the lovefest with smartphone vendors will continue, smartphones won't be the only platform that gets love from network operators.
