im not actually going to go in to all of that, simply because i dont have too, fair enough you think im talking BS, well, thats fine by me, but since i been in the business for years ive racked up a fair amount of experience, my opinion is that most windows problems are user errors, ie they screwed it up.
Just one thing about MS hardware, you are aware that apple dont make it either? they do what MS does, they design something and get someone else to build it. The xbox is intresting, the RROD issue is largely fixed but yes there appears to have been a design oversight originally, Funny thing is Sony has the same kind of issue.
Lets take the Logitec argument for a sec, assuming they do build MS gear, its amazing how crap their own products are. I know the IP of the hardware is MS but you would have thought they would have learnt something by now, no, instead they build cheep hardware which seems to have a poor desk life.
One last thing, Virus dispite the name do not magicially spread from on PC to the next, there has to be user intervention, if it be clicking on a website as you suggest or opening dodgy emails, they all requirer user intervention, same for hacking, a couple of years back i did a wee experiment, and had a bunch of PCs setup with no protection at all, half had propper training and didnt use admin accounts the other half didnt and used standard admin acounts. amazing thing was those PCs with the folk knowing what they were doing never had any issues, where as the others had serious problems, so my argument stands, if the IT admins know what they are doing as do the users most problems do not have the chance to arrise..
With current UAC protection the user needs to not only do something stupid in the first place but they need to the click on are you sure!
