Yeah, but also, I'll bet you in a couple of years the next offer from Microsoft will come with a steep discount on Office licenses.

That would mean another huge migration project with corresponding costs for training, organization, and data migration.

Those costs are never taken into account. It's always the "low" price of licensing/use/dev that is looked at, and then... you have the regret phase. Which never end because "we already invested so much", and the famous "in the long run it will be cheap... oh wait, we have a newer offer"
