I think the ad is awesome, wondering if it will actually get aired or not. Having run Windows Vista (RTM, not the earlier RC's) I have to say that I still dislike the way the UAC works. Number three that you pointed out NetRyder is a major problem, and will continue to exist, as for business I have had to run rather outdated software, that is proprietary to the company and has not seen an update since 1999, right before the y2k scare.
I have also seen the UAC quite a bit especially with to file permissions, if I run a program and it has no permissions to go into a certain directory (.NET application I wrote for class), it should throw a System.Security error, and not give me a dialog for each bloody access to something I am not allowed to access, this is especially a pain when writing networked applications in .NET as on the Vista machines at school no-one had Administrator access. We never did in XP, but in XP it would throw an error instead of thousands of dialog boxes.
I like the improvements Windows Vista has made over Windows XP, however for my needs and the needs of the school, we are back down to 2 test machines running Vista, the rest are back to Windows XP because of complaints from users. Software has to be updated, and before that happens it can be a while.
Sorry to go off into a rant, Windows Vista unfortunately has made it harder for a mixed environment to develop on machines that are locked down, at least harder than before. Especially also in references to game development and testing.
My preferred environment is FreeBSD with Xorg and Xfce 4. And my second for when I just need stuff to work, Mac OS X.
Now, in reply to people asking for viruses for the Mac, look around, there are plenty. Question is, how viable are they for distribution, for example, a worm would not do much good, as the only ones that allow root access, have to be executed by a user in some way shape or form. The month of apple bugs is over, however it contains many examples of how it could be done.
As for the two people saying they have lost respect for Apple, all good and well, really not needed in this thread, off topic, and flamebait. I know, I know, trolling is fun, however it just detracts from the overall topic, and makes it less fun to read. If all it takes is an advertisement to make you lose respect, I suggest some very good reading, from the Microsoft Get The Facts campaign, now that is some straight up bull**** marketing.
