If you accept the idea that eventually every device will have the ability to connect, the argument makes sense. Forcing the idea when it currently costs a couple-hundred dollars to do so, plus the cost of data, does not make any consumer sense at all. Where the argument does not make sense is in the reality that there is growth Wi-Fi access in areas where computers are used the most, schools, offices and homes (and coffee shops too). Coupled with traditional wireline connectivity behind all these hotspots, Wi-Fi is far more affordable as well.
In the context of a consumer device like the Amazon Kindle, the marketing framework is there to establish a relatively low-cost solution for data. However, Amazon’s plans are geared around downloading a book or two, checking email and doing light internet browsing. With their new 4G/LTE plan which costs $50 per year, Amazon customers get 250MB of data each month. That is a data plan tailored to a specific purpose.
Customers that buy other computers and tablets are not typically that narrow minded though and would rather have a bit more latitude to satisfy their data appetites.
