the comment I am replying to explicitly mentions Linux as an alternative to Windows. In any case, yes, one could use Mac, as I do, but it comes with its own issues, starting from price. I'd happily switch 100% to Linux if I didn't need to work on documents edited with Office. The online version may actually solve this, but it's still buggy as hell.
But that aside — Excel is a single application. That one app doesn’t determine an entire Corporate IT strategy.
