In the future it will be important for all computer and device systems to be compatible with each other. Companies should realize that they will not get many new customers if switching to their brand is inconvenient. People are already making apps to deal with the problems caused by incompatible operating systems, but the companies themselves should be doing more to help the people using their devices.
Economists never cease to tout the benefits to consumers of increased consumer choice, and in some sense they are right. Competition between Apple and Android-based products improves the quality of product and user experience for consumers, and this is a good thing. But too often this competition has unforeseen results that are definitely not good for the consumer, such as Apple's unwillingness to facilitate the transfer of text messages off of an Apple product to another mobile environment such as Android. This is really too bad.
Yes, individuals who switch from Apple's iPhone to Android systems should be allowed to transfer old texts to their new phone. By purchasing the iPhone, you own the device and the content on it. You should be allowed to transfer any personal information from that device to a new one at the time of your choosing.
Many people believe that if they switch from Apple's iPhone to an Android that they should be able to transfer their old texts. I disagree. Apple is in business to sell and keep customers with their iPhones. If they deem that it is not good business to allow transfers, how can we force the situation? It is their business and they have the right to run it in the way they deem fit.
