Thats why most windows users had to go out and buy a more powerful machine just to even be able to run vista. Windows is bloated to the point of bursting.

So if the mac is so resource hungry how comes I can run three operating systems simultaneously (two by VM) and not have a problem - try that on windows.

With windows, if you open internet explorer, notepad and excel together it farts, falls over and gives you the BSOD.
