M$ Vista - don't do it if you can help it

The issue of copying files at a snail's pace in the latest and greatest Microsoft OS, Vista, seems to be turning into a serious nuisance. I can't believe that the OS even escaped the Q&A phase when this issue of some basic functionality like deleting and copying files is causing such an fuss amongst users. What makes it worse is that Microsoft are dragging their feet and not releasing an official fix or offering anyone any explanations. This issue alone has stopped me from going anywhere near Vista until everyone is happy with it and there are unavoidable advantages of switching to another OS - the basic reason why I don't wanna move to MAC OSX. If it ain't broken, don't fix it.
