I think a person can find a place for anything, but I fear we get lost in looking for reasons to replace what is working for ways to solve problems. A nurse would benefit from having a medical record chart on a tablet instead of hardcopy form. An electrical engineer would not benefit from using anything less than the strongest processing power on the market. Trying to find a way to justify a tablet for an engineer would be ridiculous. Finding a better way to have current medical information complete and updated system wide in real time would be innovative.
I know people have problems with Microsoft and security, but until there are centralized security management suites that have been tested like a new form of medication, the path for many devices not running a MOS will have a steep hill to climb in order to be seen as legitimate in the professional world.
