Not Big Cities but big deployments
A lot of specialized software (200+ programs AFAIK)? getting
married, register a car, managing taxes for dogs, ...
Windows + Cytrix terminal servers (AutoCAD, where BriksCAD is
not good enough), seldomly WINE (no shareable)
Fat client software is more prone to scaling based bugs the
server software (KDE PIM currently doesnt scale and conflicts with
the way we use roaming profiles)
LibreOffice breaks as much as MS Office for new versions (the
community improves the test coverage for every release)
