"Do you know how to go about getting road tax for your car? Or register the birth of a child? Apply for a job or a college course? Hint: 2G won't get you very far."
*Why* won't 2G get me very far? None of those *needs* to be high bandwidth, content rich, data heavy, applications. Very little routine stuff does, in principle.
If some sh*thead presentation layer person has designed them badly (e.g. like the "improved" MetOffice website a year or two back) so they look Flash in the office and look carp on a low-performance link, maybe someone should redesign them for the real world.
Or better still maybe the relevant managers should be forced to live with just 2G for a few weeks.
