I'm sorry if my rant cast an aspersions on your abilities. Unintended.
The Nimba and Code Red viruses could have been prevented if the patch that Microsoft released months earlier had been installed. In fact, it was the description of the problem on Microsoft's site that gave the hackers the idea. :-(
The original goal was to make administration and all features of the server web enabled and other features open by default. Though this makes computing easier for those trying to implement solutions (like running executables in Outlook), it also makes it easier for hackers. Thus, Microsoft will be shipping OSes in the future without installing software and keeping ports closed. Safer yes. Less functional for users, yes.
The above is the default for UNIX implementations and thus, fewer hack attacks. Microsoft has reconciled itself to the fact that there people who are unfairly against Microsoft and wish it harm (Dominic??? :-) ).
If the above list didn't prove something about the quality of the product to you, then by all means continue using it.
I don't wish MS harm, anymore than I wish 'Brittney Spears' wrong. I just think it's devastating for our tech industry to have a company using illegal means to force inferior products on the market, and want the illegalities to stop.
Other than stopping MS's illegalities, I wish them no harm at all.
I'm not really a strong partisan for any particular OS. I have used the major ones (DOS/Win, Mac, Unix) and they all have pros and cons, IMHO.
