Both times I booted in to Windows over the last ~18 months were to apply for Visas on sites that wouldn't work properly with either Firefox, Chrome or Opera in Linux. With most sites I'd just move on, but for a visa application with no viable alternative... Sure, that's a problem that ought to be addressed by those sites, but it's still a possible use case.
