Another area for research involves application maintenance in the rapidly changing world of mobile platforms. While “earlyadopter” consumers are often willing to update their device and their applications, most enterprise users are less likely to do so. In many cases, their companies will have policies discouraging them from doing so, as can be seen by the slow enterprise transition away from Windows XP and Office 2003. One particularly interesting question involves the use of virtualization technology on these devices as a way to support various platforms.
