Since they migrated 1000 workstations to Linux in one
year, any simple fool can tell you it will take them 14
years to migrate all 14,000 workstations.
It's not quite the case. In the first year they would have
to look for or to port applications to Linux (that's what
they wrote somewhere). Also, Linux evolves all the time
(Wine, for example, improves), so the beginning is the slowest.
