Maybe that could be easier. If you only use what Windows XP gives you, and never use any of the provided alternatives, Windows is more than hell. It's the hottest of living hell's ever to be conceived by man, with a little help from the devil himself (Bill Gates).
In this perspective, this makes Linux look like pure heaven, which it is.
However, people who use OSS on Windows have skimmed down Windows so much that the hell freezes a bit.
And from experience, I know that myself, and many others first used OSS on Windows, then switched to Linux.
Even better: using OSS on Windows makes the switch to Linux a whole lot easier, resulting in the culture shock being less and people sticking more to Linux. And isn't that what we all want?
