I think this is a little superficial. There will be mountains of existing Word/Excel/Powerpoint documents that would need converting, as well as configured permissions structures and remotely managed laptop configurations that currently are working well. Of course anything is possible given enough time and money. The real issue isn't to do with your ageism. It's whether that time and money is best spent on this particular area.
