There is no electronic or digital difference between the data plans. Many users mistakenly defend or fail to defend the price difference on the basis of the amount of data used. In reality, a phone which can handle full HTML pages, view full screen video, upload and download email attachments and allow full keyboard typing is more efficient. This device enriches the mobile experience and carriers feel that there should be a premium for that type of service. Whether or not the price should be double is open to debate.
