Just a Theory

I'm no insider, but if I had to envision Microsoft's checklist by which they evaluated Vista's success I imagine it would look something like this:

1.) Implement unnecessary pseudo 3d alternative to alt+tab to satiate stockholder anticipation and give marketing something to play with
2.) Prevent Explorer from being able to handle more than 10 or so windows no matter how much RAM/virtual memory the user has available
3.) Do everything in our power to deprecate the creation and editing of Doom levels

If I am right, then bravo Microsoft; you are the very apex of accomplishment.
