The year of 2011 is considered as the year in which the tablet product lines emerged to the world, and specifically to the USA.
Data collection shows interesting notions. I t was found that about 90% of the tablets has WiFi access only, with no cellular access. It is quite surprising, as the cellular providers in the USA invest lots of effort and budgets for fast and wide deployment of high speed access, including to support tablet users.
So, why is that so? Why do people give up cellular access? One possible explanation for this is that web browsing by tablets is not subsided by browsing packages, so the public go to cheaper products and packages.
Another explanation is that the tablet does not necessarily satisfy the basic need for smartphone. And smartphone already include cheap browsing packages. In addition, smartphone can perform as routers for the tablets themselves, so the public does not see any advantage in paying for cellular access for its tablets.
