In Korea where I live the only way to buy anything online
at a Korean site is via MS Intenet Explorer, because
government privacy and security controls mandate certain
anti-phishing and anti-malware add-ons to be in place.
These are written with MS Active-X controls. One cannot
even use Firefox to buy ink cartridges from a Korean
on-line marketer, don't mention use internet banking.
The government imposed real-name banking laws to foil
slush funds set up secretly to avoid taxes and for
other reasons by politicians, business tycoons and
organized crime, in the names of willing relatives or
cohorts. Similarly, aside from financial transactions,
even on-line postings on Korean portal site blogs and
cafes are no longer able to be done without the
portal's recording a citizen's identity in its logs,
so that police can crack down on slander. It's a sort
of nightmare scenario from the perspective of, say,
American libertarians, but it's acceptable in the eyes
of the general population here. Different cultures.
Anyway, MS Active-X is the chosen implementation for
these controls. Korea is MS land and the Linux
community here in the Far East is more of a cult group
than it is in North America and Europe and the rest of
the world. Dual-boot will be around for a long time,
even as people continue to opt for the Linux desktop.
