OK, well in the last 4 years, I have had zero viruses, zero spyware, zero hardware issues (and I've built 3 complete systems since that time) and not had the OS (Windows XP and most recently Vista) crash a single time. The last blue screen of death I saw was running Windows ME, over 6 years ago. I use several systems for 16+ hours a day for all kinds of uses. I serve and maintain 40+ workstations (all Windows XP) daily and have not had a single OS crash in the 6+ years they have been deployed. Every single crash, unexpected reboot, etc. has been due to events beyond human control and irrespective of the platform - lighting strike, power outage, network failure, buggy application, and by FAR THE #1 CAUSE OF PROBLEMS - USER ERROR. Stupid users will cause grief on whatever system you give them.
Shows you how irrelavent such testimonials are, doesn't it (mine is 100% true BTW)? You and I both know that 'how many viruses' and 'how much spyware' one gets is 100% due to the operator - NOTHING to do with the computer or OS. You hear about Macs having less infections for two simple reasons:
1 - there are hardly any Mac users compared to Windows.
2 - there are far fewer viruses and spyware written for a Mac, because of fact #1.
It's simply odds, not by virtue of the platform.
By the flawed logic shown by many mac-fan-boys, the Timex Sinclair has the Best OS, because it has never crashed, and has never had a virus or spyware effect it. LOL
