These days I'd hope any wifi-enabled device on any OS, whether desktop or mobile, would effortlessly connect to a hotspot when available.
I think the point is, OSX seems to have been able to do it effortlessly for a lot longer than anything else, hence two whole pages of instructions to cover all eventualities in two versions of windows, versus half a page for all iterations of OSX, of which IIRC there were 5, or maybe 6, at the time Windows Vista was MS' most up-to-date OS.
Anyways, it's all a bit of fun, those of us with Macs don't really need to post threads to vindicate our choice. We know we're superior.
