The financial institutions say yes. From my point of view as a customer of a financial institution, I say no. Often, customers go to their financial institutions, where they are given tools that the institutions guarantee are secure. The clients go home or to work with a tool, an application, to access the system, but they really do not know how it works. All the risk then falls on their shoulders. If they make a mistake, it's their fault, not the fault of the financial institution, which has no problem proving it.
That is the shame. I was somewhat preaching the need to know one's operating system. Will the next Andoid phone be up to the task? People will not know how to use it any better. The training will focus on one application only and people will have to adapt when the application changes its look and its feel. This is what the market has been forcing on us for 30 or so years. As soon as the look and feel of an application changes, you have to work at adapting to it. There is no update, and no one holds our hand to help us become familiar with the new application.
