I disagree, I used Linux for a long time when the alternative was either Win9x, NT or 2k... Back than I would have thought that Linux was better, but now I would have to say that I prefer XP over Linux. As for security problems, that's where updating comes in handy. Besides, Linux has it's exploits as well, they just aren't as well known because of the fact that less people use it and it's not in the spotlight like MS is.
