Bankrolling ujpgrades
"So, will they go on bankrolling the likes of Microsoft and Excel (or even Office 365)?"
Yep, as long as MS keeps inventing new "standards" like xlxs. Or as long as crap software like Sage keeps insisting on having Excel installed in order to generate reports (output a freaking .csv guys! or at least let me set up the reports on the server without expecting Excel to be installed on the Sage server... good lord).
