In the company I work for, 99% of people spend their days in some combination of teams, outlook, word, excel and chrome. Word is basically for random text which is expected to last longer than an email or for carting around screenshots, Excel is for people who need five lines in a table. All these things work fine in a browser. The other 1% are either accountants who actually use Excel for what it was made, designers, etc.
Among those 99% there are a bunch of people shouting from the rooftops how much security is a priority for the company, so they run around in circles trying to secure a fundamentally insecure OS, while at the same time being scared shitless to update anything for fear of "breaking something". I'm convinced that moving to something like Chrome OS would improve these 99% of people's lives tremendously. But it's not what they're used to, so everybody just keeps on going down the same path.
