Well first of all, most people won't switch, and even more won't use Linux, let alone even know what Linux is. Secondly, I think that people just use the OS that's installed with the computer when they buy it, and that's going to be Vista. Third, sure Windows 95/98 instability combined with the bitterness towards Microsoft's success led to the feelings about Windows that still seem to spill over into present day computing. But to be fair, Windows XP is quite stable. Sure that there are thousands of viruses written specifically for it, but it's operating stability is compariable to just about any workstation, including OS X. There is no reason to think that Windows Vista will be any less stable then XP, and should prove to be even more stable. Looking at one instance of Microsoft's Operating System history with poor stability and then labeling the whole Windows franchise unstable is not very fair. I could point out some old Mac OSes that were just as bad. OS 7 was pretty scetchy...
